Description

Liquid crystal display panel and method of manufacturing same

The present invention relates to a liquid crystal display panel, and in particular to a liquid crystal display panel and a method of fabricating the same.

Liquid crystal displays have been widely used in recent years due to their low power consumption, low manufacturing cost and no radiation. The thin film transistor liquid crystal display panel mainly comprises a color filter substrate and an array substrate provided on the box, and a liquid crystal layer filled between the color filter substrate and the array substrate. The process of the liquid crystal display panel can be filled with liquid crystal by using a drop drop technique (One Drop Fill, ODF for short), for example, the liquid crystal is dropped into the display area of the pre-made color filter substrate or the array substrate, and the substrate is dropped on the substrate. The peripheral area is coated with a sealant; after the sealant coating and liquid crystal dripping are completed, the color filter substrate and the array substrate are precisely aligned, and the sealant is cured to achieve the bonding of the two substrates.

In the process of achieving the bonding of the two substrates, the liquid crystal is usually dripped in the central portion of the display area, and gradually spreads from the center of the display area to the periphery. In the process of diffusing the liquid crystal around the display area, if the sealant located in the peripheral area is in contact with the liquid crystal before being completely cured, the incompletely cured sealant may contaminate the liquid crystal, thereby causing defects such as poor display quality of the liquid crystal display panel. .

Figure 1 is a cross-sectional view of a prior art liquid crystal display panel. Please refer to FIG. 2 at the same time. FIG. 2 is a partial enlarged view of FIG. 1. As shown in FIG. 1 and FIG. 2, in order to eliminate the possible contamination of the liquid crystal by the incompletely cured sealant, the prior art is located in the periphery. The region forms a blocking frame 750 having a trapezoidal cross section. In order to avoid contact with the incompletely cured sealant 730 during the diffusion of the liquid crystal 740 from the central portion of the display area to the periphery; after the color filter substrate 710 and the array substrate 720 are paired, the two substrates press the blocking frame up and down. The liquid crystal 740 of the display area is completely isolated from the sealant 730 of the peripheral area.

During the implementation of the present invention, the inventors have found that the prior art provides a technical solution for the barrier frame in the peripheral region of the liquid crystal display panel, which reduces the probability that the liquid crystal display panel will cause contamination of the liquid crystal by the incompletely cured sealant in the process of the cartridge. There are still display problems surrounding the whitening. The reason for the experiment is that when the liquid crystal contacts the frame rubber which is not completely cured, the resin in the sealant is analyzed, and the resin component is the main cause of the display problem of the peripheral whitening. In the prior art, since the blocking frame 750 has a trapezoidal cross section, assuming that the bottom angle of the trapezoid is α, and the liquid crystal located on the slope of the blocking frame 730 has a flow velocity m, the dividing velocity in the vertical direction is m*sinα, and the partial velocity in the horizontal direction is m*cosα, so the blocking frame in the prior art can only block part of the flow rate, and the contact time of the liquid crystal with the incompletely cured frame seal is limited.

The present invention provides a liquid crystal display panel to improve the white display problem of the conventional liquid crystal display panel.

The liquid crystal display panel of the present invention comprises a first substrate on which a plurality of spacers are disposed, a second substrate disposed opposite to the first substrate, and a liquid crystal layer on the first substrate and the second substrate. Between and in contact with the spacer; a liquid crystal retaining wall disposed on the first substrate, the liquid crystal retaining wall is disposed around the liquid crystal layer, the sidewall of the liquid crystal retaining wall contacting the liquid crystal layer and the first The angle at which the substrate is formed is an acute angle.

In an embodiment of the present invention, the liquid crystal retaining wall is an inverted trapezoid.

In an embodiment of the present invention, the angle formed by the two sides of the inverted trapezoid of the liquid crystal retaining wall and the first substrate is an acute angle.

In an embodiment of the present invention, an angle side formed by the two sides of the inverted trapezoid of the liquid crystal retaining wall and the first substrate is an acute angle, and the other side is a right angle.

In still another embodiment of the present invention, the acute angle is not less than 45 degrees.

In an embodiment of the present invention, the acute angle is no greater than 85 degrees.

In another embodiment of the present invention, the liquid crystal retaining wall is disposed on the same substrate as the sealant.

In still another embodiment of the present invention, the liquid crystal retaining wall and the sealant are respectively disposed on different substrates.

In an embodiment of the present invention, the liquid crystal retaining wall has a certain distance from the sealant.

In another embodiment of the present invention, the liquid crystal retaining wall is formed simultaneously with the spacer.

The method for manufacturing the liquid crystal retaining wall further includes: coating a photoresist layer on the first substrate; placing the first substrate in an oven and pre-baking the photoresist layer to make the photoresist layer The upper surface is cured; the photoresist layer on which the upper surface has been cured is exposed by a photomask; and the photoresist layer is finally developed and etched.

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

Fig. 3 is a schematic view of the see-through color filter substrate 100 of the liquid crystal display of the present invention. As shown in FIG. 3, the liquid crystal display of the present invention comprises a color filter substrate 100, an array substrate 200, and a liquid crystal layer 400 interposed between the color filter substrate 100 and the array substrate 200. The liquid crystal layer 400 is composed of a liquid crystal layer 400. The liquid crystal layer 500 and the sealant 300 are disposed on the array substrate 200. The liquid crystal layer 400, the liquid crystal retaining wall 500 and the sealant 300 are disposed on the array substrate 200. The liquid crystal layer 400, the liquid crystal retaining wall 500 and the sealant 300 have a color thereon. The filter substrate 100, wherein the liquid crystal barrier 500 can be disposed on the color filter substrate 100 or the array substrate 200, and the sealant 300 can be disposed on the color filter substrate 100 or the array substrate 200, or the liquid crystal retaining wall 500 and The sealant 300 can be disposed on the color filter substrate 100 or the array substrate 200 at the same time. The liquid crystal retaining wall 500 is disposed around the liquid crystal layer 400. The sealant 300 is disposed around the liquid crystal retaining wall 500. When the liquid crystal is dropped on the color filter substrate 100, the liquid crystal retaining wall 500 is also disposed on the liquid crystal retaining wall 500. On the color filter substrate 100, on the other hand, when the liquid crystal is dropped on the array substrate 200, the liquid crystal barrier 500 is disposed on the array substrate 200.

Please refer to Figure 3 and Figure 4A at the same time. Figure 4A shows the structure of the liquid crystal retaining wall of this case. It is assumed that liquid crystal is dropped on the color filter substrate 100, and at this time, the liquid crystal barrier 500 is also disposed on the color filter substrate 100. The liquid crystal instillation may also be on the array substrate 200, and the liquid crystal retaining wall 500 is also disposed on the array substrate 200. In the following explanation, liquid crystal is dropped on the color filter substrate 100 as an example. The liquid crystal is usually dropped on the display area of the color filter substrate 100, more specifically, in the central portion of the display area of the color filter substrate 100. The size of the central portion is determined by the size of the panel, and the liquid crystal layer 400 is The display area gradually spreads around. When the liquid crystal layer 400 is diffused to the liquid crystal barrier 500, since the angle between the side of the liquid crystal barrier 500 contacting the liquid crystal layer 400 and the color filter substrate 100 is an acute angle, it is assumed that the liquid crystal layer 400 encounters the liquid crystal barrier 500. When the velocity along the sidewall of the retaining wall is x, the theoretical velocity of the liquid crystal layer 400 in the horizontal direction is x*cos θ, and the dividing velocity in the vertical direction is x*sin θ, but since θ is an acute angle, The partial velocity x*cos θ of the liquid crystal layer 400 in the horizontal direction is opposite to the traveling direction of the liquid crystal layer 400. Therefore, the liquid crystal retaining wall 500 can effectively delay the contact time of the liquid crystal layer 400 with the sealant 300, so that the sealant has sufficient time to completely cure, thereby preventing the liquid crystal layer 400 from completely contacting the uncured sealant 300. This causes problems in the surrounding whitening. In the embodiment, the liquid crystal retaining wall 500 is an inverted trapezoid, and the angle formed by the two sides of the inverted trapezoid of the liquid crystal retaining wall 500 and the color filter substrate 100 is an acute angle. Of course, the liquid crystal retaining wall 500 is not limited to the inverted trapezoid, as long as the angle between the sidewall of the liquid crystal retaining wall 500 contacting the liquid crystal layer 400 and the substrate on which it is located is an acute angle, wherein the acute angle is not less than 45 degrees and not more than 85 degrees.

Please refer to FIG. 3 and FIG. 4B again. FIG. 4B is a schematic structural view of another liquid crystal retaining wall in the present case. It is assumed that liquid crystal is dropped on the color filter substrate 100, and at this time, the liquid crystal barrier 500 is also disposed on the color filter substrate 100. Of course, the liquid crystal instillation can also be on the array substrate 200, and the liquid crystal retaining wall 510 is also disposed on the array substrate 200. In the following explanation, liquid crystal is dropped on the color filter substrate 100 as an example. The liquid crystal is usually dropped on the display area of the color filter substrate 100, more specifically, in the central portion of the display area of the color filter substrate 100. The size of the central portion is determined by the size of the panel, and the liquid crystal layer 400 is The display area gradually spreads around. When the liquid crystal layer 400 is diffused to the liquid crystal barrier 500, since the angle between the side of the liquid crystal barrier 500 contacting the liquid crystal layer 400 and the color filter substrate 100 is an acute angle, it is assumed that the liquid crystal layer 400 encounters the liquid crystal barrier 500. When the velocity along the sidewall of the retaining wall is y, the dividing velocity of the liquid crystal layer 400 in the horizontal direction is y*cos θ, and the dividing velocity in the vertical direction is y*sin θ. Since θ is an acute angle, the liquid crystal layer 400 The partial velocity y*cos θ in the horizontal direction is opposite to the traveling direction of the liquid crystal layer. Therefore, the liquid crystal retaining wall 510 can effectively delay the contact time of the liquid crystal layer 400 with the sealant 300, so that the sealant has sufficient time to completely cure, thereby preventing the liquid crystal layer 400 from completely contacting the uncured sealant 300. This causes problems in the surrounding whitening. In the embodiment, the liquid crystal retaining wall 500 is an inverted trapezoid, and the angle formed by the two sides of the inverted trapezoid of the liquid crystal retaining wall 500 and the color filter substrate 100 is an acute angle. Of course, the liquid crystal retaining wall 500 is not limited to the inverted trapezoid, as long as the angle between the sidewall of the liquid crystal retaining wall 500 contacting the liquid crystal layer 400 and the substrate on which it is located is an acute angle, wherein the acute angle is not less than 45 degrees and not more than 85 degrees.

5A-5D is a manufacturing method of the liquid crystal retaining wall of the present invention, and the liquid crystal retaining wall 500 is an inverted trapezoid as an example. First, a photoresist layer 510 is coated on the color filter substrate 100 as shown in FIG. 5A. The photoresist layer 510 comprises a UV photopolymer and a thermosetting polymer, and then the color filter substrate 100 is placed in an oven and The photoresist layer 510 is pre-baked such that the upper surface of the photoresist layer 510 forms a hardened layer 520 as shown in FIG. 5B, and the photoresist layer 510 under the hardened layer 520 is still in an uncured state. At this time, referring to FIG. 5C again, the hardened layer 520 on the upper surface of the photoresist layer 510 and the uncured photoresist layer 510 located under the hardened layer 520 are exposed by the mask 800. Finally, the photoresist layer is developed and etched to obtain an inverted trapezoidal liquid crystal barrier 500 as shown in Fig. 5D. Of course, the liquid crystal retaining wall 500 can also be disposed on the array substrate 200 in the same manner, and details are not described herein again. It should be noted that the liquid crystal retaining wall 500 of the present invention is formed at the same time as the spacer in the surface, so the liquid crystal retaining wall 500 does not need to increase the manufacturing process. Since the liquid crystal retaining wall 500 is formed simultaneously with the in-plane spacer, when the retaining wall is disposed on the color filter substrate 100, the in-plane spacer is also disposed on the color filter substrate 100; when the retaining wall is disposed at On the array substrate 200, in-plane spacers are also disposed on the array substrate 200.

After the array substrate 201 and the color filter substrate 101 are assembled, the sealant 301 is cured to bond the two substrates. In the bonding process, although the liquid crystal layer 401 is diffused from the central portion to the periphery, when it encounters the liquid crystal barrier 501, the sidewall of the liquid crystal barrier 501 contacting the liquid crystal layer and the color filter substrate 101 is an acute angle, so the direction of the dividing speed of the liquid crystal layer 401 in the horizontal direction is opposite to the traveling direction of the liquid crystal layer 401 as described above, and a spacing d is further provided between the liquid crystal retaining wall 501 and the sealant 301. The spacing d further delays the time when the liquid crystal layer 401 is in contact with the sealant 501, so that the sealant 301 can be cured more fully in time, so that the resin component in the sealant is not contacted by the liquid crystal. The precipitation causes display problems in the surrounding whitening.
