Color filter substrate and liquid crystal display

The present invention relates to a color filter substrate and a liquid crystal display, and more particularly to a color filter substrate and a liquid crystal display capable of generating two different transmittances in one pixel.

Fig. 1 is a schematic view showing a partial cross section of a conventional liquid crystal display. As shown in FIG. 1, the liquid crystal display 90 includes a filter substrate 912 and an active device substrate 914 facing each other, and a liquid crystal layer 916 is interposed between the substrates. The liquid crystal layer 916 employs a negative dielectric anisotropy liquid crystal material such that the liquid crystal molecules are vertically aligned when no voltage is applied. A switching element (not shown) such as a thin film transistor (TFT) and a pixel electrode 922 are formed on the transparent substrate 928 of the active device substrate 914. A color filter 930 is formed on the transparent substrate 926 of the filter substrate 912, and a common electrode 924 is formed on the color filter 930. The color filter 930 includes a light-shielding black matrix layer 934 and a filter track region 932.

However, liquid crystal displays with a vertical alignment structure have a color washout phenomenon when viewed from a large viewing angle. For example, when viewed from a large viewing angle, the skin color tends to be lighter blue or brighter white. The general solution divides a pixel into several regions, and then uses a dual gate line, dual data line (T-T type), common voltage swing, thin film transistor. Techniques such as partial pressure and capacitance coupling (C-C type) reduce this color shift. However, there are disadvantages in these solutions. For example, dual data lines and swing common voltage technologies require additional integrated circuits (ICs) and components to increase process time and material cost. The thin film transistor voltage division and capacitive coupling technology can solve the color shift phenomenon without additional IC, but it will reduce the aperture ratio due to the additional thin film transistor. In addition, capacitive coupling techniques create self-coupled capacitance due to floating electrodes, causing severe image-sticking.

In addition, when a liquid crystal display is touched with a finger, a white or black embossing (ie, a finger print mura) phenomenon occurs due to a disordered liquid crystal state. It is generally known that the liquid crystal state in the liquid crystal display returns to the original state of the tilting state in the direction of the electric field, and the reaction time is long, so that the embossing phenomenon is observed by the human eye. A common solution is to increase the density of the photo spacer or to form a patterned transparent ITO electrode on the active device substrate 914, but the former causes slower liquid crystal injection and increases the cost of working. The latter is a reduction in the aperture ratio.

Accordingly, it is an object of an embodiment of the present invention to provide a color filter substrate and a liquid crystal display capable of alleviating the perceived color shift phenomenon when viewed from a larger viewing angle. An object of an embodiment is to provide a color filter substrate and a liquid crystal display capable of reducing embossing.
