1 is a plan view of a liquid crystal display according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the liquid crystal display includes first and second substrates 100 and 200. The first substrate 100 includes gate lines and data lines. The gate lines and the data lines cross each other and define a plurality of pixel regions. The plurality of pixel areas have the same structure and perform the same function. Hereinafter, a structure of one pixel area PA among the plurality of pixel areas will be described.

The pixel area PA is defined as an area surrounded by the first gate line 111, the second gate line 112, and the first and second data lines 141 and 142. The pixel area PA is divided into an upper first pixel area PA1 and a lower second pixel area PA2. The first and second gate lines 111 and 112 extend along a first direction D1 parallel to an imaginary line that bisects between the first and second pixel areas PA1 and PA2. The first and second data lines 141 and 142 are bent at the boundary between the first and second pixel areas PA1 and PA2. That is, the first and second data lines 141 and 142 extend along the second direction D2 in the first pixel area PA1 and extend along the third direction D3 in the second pixel area PA2. . The second and third directions D2 and D3 are symmetrical with respect to the first direction D1. The angle in which the second direction D2 or the third direction D3 is inclined with respect to the first direction D1 is preferably about 60 to 85 °.

The pixel area PA includes the thin film transistor T and the pixel electrode 160. The thin film transistor T may include a gate electrode 110g branched from the first gate line 111, a source electrode 140s branched from the first data line 141, and a drain electrode 140d spaced apart from the source electrode 140s. ). The drain electrode 140d is electrically connected to the pixel electrode 160 through the contact hole 150h.

The pixel electrode 160 includes first sub electrodes 161 and a first connection electrode 162. The first sub electrodes 161 are parallel to the first and second data lines 141 and 142. That is, the first sub electrodes 161 extend along the second direction D2 in the first pixel area PA1 and extend along the third direction D3 in the second pixel area PA2. The first sub electrodes 161 are each spaced apart from each other.

The first connection electrode 162 extends along the first direction D1 and connects the first sub electrodes 161 to each other. In FIG. 1, the first connection electrode 162 is shown below the second pixel area PA2, but there is no limitation according to the position of the first connection electrode 162 in the pixel area PA. For example, the first connection electrode 162 may be disposed on the boundary portion of the first and second pixel areas PA1 and PA2 or the upper portion of the first pixel area PA1 and spaced apart from each other. Can connect Alternatively, two or more first connection electrodes 162 may be provided in each of the first and second pixel areas PA1 and PA2.

The common substrate 240 is provided on the second substrate 200. Since the first and second substrates 100 and 200 face up and down, the common electrode 240 overlaps with other components of the first substrate 100. In FIG. 1, the common electrode 240 is illustrated in dotted lines so that the overlapping portion is more clearly displayed.

The common electrode 240 includes second sub electrodes 241 and a second connection electrode 242. The second sub electrodes 241 extend in parallel with the first sub electrodes 161. That is, the second sub electrodes 241 extend in a bent direction along the second and third directions D2 and D3. The second sub electrodes 241 are each spaced apart from each other. In addition, the first and second sub electrodes 161 and 241 are alternately disposed. The second connection electrode 242 connects each of the second sub electrodes spaced apart from each other.

As illustrated in FIG. 1, the pixel electrode 160 is positioned inside the pixel area PA. Therefore, pixel electrodes belonging to different pixel areas PA are separated from each other. In contrast, the common electrode 240 is integrally formed on the entire surface of the second substrate 200. That is, second connection electrodes belonging to different pixel areas PA are connected to each other.

FIG. 2 is a cross-sectional view taken along the line II ′ of FIG. 1.

Referring to FIG. 2, a gate insulating layer 120 covering the gate electrode 110g is formed on the first substrate 100. The semiconductor layer 130 is formed on the gate insulating layer 120 to overlap with the gate electrode 110g. The semiconductor layer 130 includes an active layer 131 and an ohmic contact layer 132. The active layer 131 is made of amorphous silicon, and a channel is formed when the thin film transistor T is operated. The ohmic contact layer 132 is made of amorphous silicon containing impurities. The ohmic contact layer 132 is divided into two parts, and the source electrode 140s and the drain electrode 140d are formed along the separated two parts. The source electrode 140s and the drain electrode 140d are covered with a passivation layer 150 covering the entire surface of the first substrate 100. In the passivation layer 150, a contact hole 150h exposing the drain electrode 140d is formed. The pixel electrode 160 is electrically connected to the drain electrode 140d through the contact hole 150h on the passivation layer 150. The pixel electrode 160 is covered with a first alignment layer 170 covering the entire surface of the first substrate 100.

The light blocking layer pattern 210, the color filter 220, the overcoat layer 230, the common electrode 240, and the second alignment layer 250 are formed on the second substrate 200. The light blocking film pattern 210 covers the boundary between the thin film transistor T and the pixel area PA and blocks light transmission in the corresponding area. A portion corresponding to the pixel area PA is opened in the light blocking film pattern 210, and the opened portion is filled by the color filter 220. The color filter 220 includes red, green, and blue filters alternately corresponding to the three primary colors of light for each pixel area PA. By combining the red, green, and blue filters, an image having various colors may be realized. The overcoat layer 230 covers the light blocking layer pattern 210 and the upper portion of the color filter 220. The overcoat layer 230 makes the surface of the second substrate 200 flat by eliminating the height difference between the light blocking film pattern 210 and the color filter 220. The common electrode 240 is positioned on a portion of the overcoat layer 230, and a second alignment layer 250 is formed thereon. The liquid crystal layer 300 having the liquid crystal is interposed between the first and second alignment layers 170 and 250.

3 is a cross-sectional view taken along the line II-II ′ of FIG. 1.

Referring to FIG. 3, the first sub-electrodes 161 of the pixel electrode 160 and the second sub-electrodes 251 of the common electrode 240 are alternately disposed. In operation of the liquid crystal display, a data voltage that changes in response to an image is applied to the pixel electrode 160, and a constant common voltage is applied to the common electrode 240. Due to the difference between the data voltage and the common voltage, an electric field is formed in the liquid crystal layer 300. As shown in FIG. 3, the electric field is formed in a curved shape (dotted line) connecting between the first sub electrode and the second sub electrode which are adjacent to each other. Since the liquid crystal has dielectric anisotropy, the arrangement direction varies depending on the electric field.

4A and 4B are plan views illustrating an arrangement of positive dielectric anisotropy liquid crystals in first and second pixel regions, respectively, when the liquid crystal display of FIG. 1 is operated.

4A and 4B, the liquid crystal 310 has positive dielectric anisotropy. In the state in which the electric field is not applied, the liquid crystal 310 is vertically arranged. The liquid crystal 310 has an elliptic shape having a long axis and a short axis, and the arrangement direction of the liquid crystal 310 is defined according to the direction of the long axis. The arrangement state of the liquid crystal 310 may be controlled through the first and second alignment layers 170 and 250.

The first and second alignment layers 170 and 250 are subjected to a rubbing process in the manufacturing process. During the rubbing, a roller wound around the surface of the rubbing cloth is rolled on the surfaces of the first and second alignment layers 170 and 250. The initial arrangement direction of the liquid crystal 310 may be adjusted according to the rolling direction. When the liquid crystal 310 is initially vertically arranged, the rubbing also proceeds in the initial arrangement direction of the liquid crystal 310. However, the rubbing directions of the first and second alignment layers 170 are opposite to each other. For example, when the first alignment layer 170 is rubbed downward from above, the second alignment layer 250 is rubbed downward from upward.

When the data voltage and the common voltage are applied to the first and second sub electrodes 161 and 241, the electric field E is formed. The electric field E is formed in a direction crossing the adjacent first and second sub-electrodes in plan view. In the first pixel area PA1, the electric field E is formed in a direction perpendicular to the second direction D2, and in the second pixel area PA2, the electric field E is perpendicular to the third direction D3. Is formed in the direction.

Since the liquid crystal 310 has positive dielectric anisotropy, the liquid crystal 310 is arranged side by side with the electric field E. The liquid crystal 310 is arranged perpendicular to the second direction D2 in the first pixel area PA1 and is perpendicular to the third direction D3 in the second pixel area PA2.

As described above, the liquid crystal display controls the arrangement direction of the liquid crystal 310 by adjusting the electric field (E). The transmittance of light passing through the liquid crystal 310 varies according to the arrangement direction of the liquid crystal 310. As a result, the liquid crystal display displays an image corresponding to the transmittance while controlling the arrangement direction of the liquid crystal 310. In addition, since the alignment directions of the liquid crystals 310 are different in the first pixel area PA1 and the second pixel area PA2, the first and second pixel areas PA1 and PA2 compensate for mutual optical characteristics. Improve the operating characteristics of the liquid crystal display device. For example, when an observer views the liquid crystal display from a side of a predetermined direction, the image from the second pixel area PA2 may be viewed even if the image from the first pixel area PA1 is not viewed in the corresponding direction. As a result, the image may be viewed even in the predetermined direction in which the conventional image is not viewed. In particular, when the first and second sub electrodes 161 and 241 form an angle of about 60 to 85 degrees with respect to the row direction, the electric field E is formed at an angle of about 5 to 30 degrees with respect to the row direction. Therefore, the liquid crystal 310 can rotate in a substantially parallel state with respect to the first and second substrates 100 and 200, and the viewing angle is further improved.

In addition, the above structure and driving method has the following advantages. Since the first and second sub electrodes 161 and 241 are spaced apart from each other, a portion where the pixel electrode 160 and the common electrode 240 overlap with each other is minimized. The pixel electrode 160, the liquid crystal 310, and the common electrode 240 form a liquid crystal capacitor. Since the overlapping portion is minimized, the liquid crystal capacitor has a small capacitance value, which is advantageous for high frequency driving.

5A and 5B are plan views illustrating an arrangement of negative dielectric anisotropy liquid crystals in first and second pixel regions, respectively, when the liquid crystal display of FIG. 1 is operated.

5A and 5B, the liquid crystal 310 has negative dielectric anisotropy. The first and second alignment layers 170 and 250 are rubbed in the horizontal direction, and the liquid crystal 310 is arranged in the same direction as the rubbing. The rubbing directions of the first and second alignment layers 170 are opposite to each other. For example, when the first alignment layer 170 is rubbed in the left direction, the second alignment layer 250 is rubbed in the right direction.

When the data voltage and the common voltage are applied to the first and second sub electrodes 161 and 241, the electric field E is formed. In the first pixel area PA1, the electric field E is formed in a direction perpendicular to the second direction D2, and in the second pixel area PA2, the electric field E is a direction perpendicular to the third direction D3. Is formed. Since the liquid crystal 310 has negative dielectric anisotropy, the liquid crystal 310 is arranged in a direction perpendicular to the electric field E. FIG. The liquid crystal 310 is arranged side by side in the second direction D2 in the first pixel area PA1, and is arranged side by side in the third direction D3 in the second pixel area PA2.

As described above, the liquid crystal display device controls the arrangement direction of the liquid crystal 310 by adjusting the electric field E, so that a corresponding image is displayed. In addition, since the arrangement directions of the liquid crystals 310 are different in the first pixel area PA1 and the second pixel area PA2, the first and second pixel areas PA1 and PA2 compensate for mutual optical characteristics. As a result, the viewing angle of the liquid crystal display device is increased.

On the other hand, as described below, the liquid crystal display device of the present embodiment prevents the display signal from being degraded due to the interference of the video signal.

6 is an enlarged plan view of a portion of the liquid crystal display of FIG. 1. FIG. 6 schematically illustrates only a part of the pixel area without omitting some components for convenience of description.

Referring to FIG. 6, two first sub-electrodes 161 are provided and three second sub-electrodes 241 are provided. The two first sub-electrodes 161 may be classified as a left first sub-electrode 161a and a right first sub-electrode 161b. In addition, the three second sub electrodes 241 may be divided into a left second sub electrode 241a, a center second sub electrode 241b, and a right second sub electrode 241c.

As shown in FIG. 6, the left second sub-electrode 241a and the right second sub-electrode 241c are positioned at the boundary portion (dotted line display) of the pixel region. The central second sub-electrode 241b is positioned at the center of the pixel area. The first and second sub electrodes 161 and 241 are alternately disposed, and the left first sub electrode 161 a is positioned between the left second sub electrode 241 a and the center second sub electrode 241 b. The right first sub-electrode 161b is positioned between the center second sub-electrode 241b and the right second sub-electrode 241c.

Therefore, the left first sub-electrode 161a and the right first sub-electrode 161b are spaced apart from the boundary of the pixel area by a predetermined distance d. As such, when the first sub-electrodes 161 are spaced apart from the boundary of the pixel area, the display quality of the liquid crystal display may be improved.

In operation of the liquid crystal display, a gate signal is transmitted along the gate lines, and the thin film transistor T is turned on by the gate signal. In addition, a data signal is transmitted along the data lines, and the turned on thin film transistor T applies a data voltage corresponding to the data signal to the pixel electrode 160. However, in the process of transmitting a data signal for displaying a next image along the data line, coupling may occur between a data voltage displaying a current image already applied to the pixel electrode 160. As a result, the data voltage may be distorted to reduce display quality of the image.

Therefore, in order to prevent distortion of the data voltage, the pixel electrode 160 may be spaced apart from the data lines. The data lines are located at the boundary of the pixel area. According to the present exemplary embodiment, the left first sub-electrode 161a and the right first sub-electrode 161b constituting the pixel electrode 160 are spaced apart by a predetermined distance d from the boundary portion of the pixel region. As a result, the pixel electrode 160 can be sufficiently spaced apart from the data lines, and the display quality is improved by preventing the data voltage from being distorted.

7 is a plan view of a liquid crystal display according to another exemplary embodiment of the present invention.

FIG. 7 schematically illustrates only a part of the pixel area, in which the structure and operation process of the liquid crystal display for the portion not shown are the same as those of the previous embodiment.

Referring to FIG. 7, the liquid crystal display includes first and second sub electrodes 161 and 241 formed on different substrates, respectively. Three first sub-electrodes 161 are provided and four second sub-electrodes 241 are provided. Two second sub-electrodes positioned at the outermost sides of the second sub-electrodes 241 are positioned at boundary portions (dotted lines) of the pixel area. Except for being positioned at the boundary portion, the remaining two second sub electrodes are positioned at the center portion of the pixel area. Each of the first sub electrodes 161 is positioned between each of the second sub electrodes 241. Among the first sub-electrodes 161, two first sub-electrodes that are not positioned at the center of the pixel area are spaced apart from the boundary of the pixel area by a predetermined distance. As a result, the first sub electrodes 161 may be sufficiently spaced apart from the data lines positioned at the boundary of the pixel area, and the display quality of the liquid crystal display device is improved.

The above operating characteristics are applied regardless of the number of the first and second sub electrodes 161 and 241. That is, when the number of first and second sub-electrodes 161 and 241 is two and three, respectively (see FIG. 6) or when the number of the first and second sub-electrodes 161 and 241 is three and four, respectively. In addition to the above (see FIG. 7), a larger number may be applicable. 6 and 7, even if the number of the first and second sub electrodes 161 and 241 increases, the display quality of the liquid crystal display may be improved if only the following requirements are satisfied.

That is, the first and second sub electrodes 161 and 241 are alternately disposed with each other, and the second sub electrodes 241 are provided with one more than the total number of the first sub electrodes 161. Each of the first sub electrodes 161 is positioned between two second sub electrodes adjacent to each other. Under this structure, the second sub-electrode positioned at the outermost of the second sub-electrodes 241 is positioned at the boundary of the pixel region, and the first sub-electrode positioned at the outermost of the first sub-electrodes 161 is the pixel. It is spaced a predetermined distance from the boundary of the area. On the other hand, since the number of the first sub-electrodes 161 constituting the pixel electrode 160 is reduced under such a structure, the aperture ratio of the pixel region is increased.

In FIG. 6 and FIG. 7, the second sub-electrode positioned at the outermost of the second sub-electrodes 241 completely overlaps the boundary of the pixel area. It does not have to overlap the boundary. For example, the outermost second sub-electrode may be positioned as close to the boundary of the pixel area as possible while partially overlapping the boundary of the pixel area or not overlapping the boundary of the pixel area. Even in such a case, the first sub-electrodes 161 may be sufficiently spaced apart from the boundary of the pixel area, thereby improving display quality.

8 is a plan view of a liquid crystal display according to another exemplary embodiment of the present invention. In the present embodiment, the same reference numerals are used for the same components as in the previous embodiment, and detailed description of these overlapping components will be omitted.

Referring to FIG. 8, the liquid crystal display includes first and second substrates 100 and 200. The first substrate 100 includes first and second gate lines 111 and 112 extending in the first direction D1 and first and second data lines 141 and 142 extending in the fourth direction. One pixel area PA is defined by the first gate line 111, the second gate line 112, and the first and second data lines 141 and 142. The pixel area PA includes the thin film transistor T and the pixel electrode 160. The pixel electrode 160 includes first sub electrodes 161 extending in the fourth direction D4 and a first connection electrode 162 connecting the first sub electrodes 161.

The common substrate 240 is provided on the second substrate 200. The common electrode 240 includes second sub electrodes 241 extending in the fourth direction D4 and a second connection electrode 242 connecting the second sub electrodes 241.

The first and second sub electrodes 161 and 241 are separated from each other, and each first sub electrode is positioned between adjacent second sub electrodes. Accordingly, the second sub-electrode positioned at the outermost of the second sub-electrodes 241 is positioned at the boundary of the pixel region, and the first sub-electrode positioned at the outermost of the first sub-electrodes 161 is the pixel region. It is spaced apart from the boundary of PA by a predetermined distance. As a result, it is possible to prevent the display voltage from being degraded due to the interference between the data voltage of the current video and the data voltage of the next video.

According to the display panel according to the present exemplary embodiment, the viewing angle of the liquid crystal display may be increased and the display quality of the image may be improved. While some embodiments have been described in terms of examples above, those skilled in the art can variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below.
