Liquid crystal display device and manufacture method of color film substrate thereof

Abstract

The invention discloses a liquid crystal display device and a manufacture method of a color film substrate thereof. The liquid crystal display device comprises an array substrate, a color film substrate and a liquid crystal layer arranged between the array substrate and the color film substrate, wherein the color film substrate comprises a substrate, a color pixel graph and a black matrix graph, wherein the color pixel graph is arranged on the substrate in a matrix mode; the black matrix graph comprises a transverse structure and a vertical structure, is supported between the array substrate and the color film substrate, is in partial contact with the array substrate and is used for shading light and keeping the liquid crystal box thickness between the array substrate and the color film substrate. Compared with columnar spacers in the prior art, the black matrix graph of the color film substrate increases the supporting area so that the stability of the liquid crystal box thickness is increased to a large degree, and thereby, TOUCH MURA badness is effectively improved, and light leak badness and contrast reduction phenomena brought by observing from different viewing angles are effectively prevented.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacturing, in particular to a liquid crystal display device and a method for manufacturing a color filter substrate. Background technique [0002] With the development of liquid crystal display technology, thin film transistor liquid crystal display devices (TFT LCD) featuring low power consumption, relatively low manufacturing cost and no radiation have become the mainstream of the liquid crystal display market. TFT LCD is formed by injecting liquid crystal material between the array substrate and the color filter substrate after the array substrate and the color filter substrate are boxed together. Usually, TFT LCD uses the optical anisotropy and birefringence of liquid crystal molecules to display images. TFT LCD changes the orientation of liquid crystal molecules by applying a voltage to the electrodes on the two substrates to generate an electric field, thereby controlling the amoun...

AI Technical Summary

Problems solved by technology

[0004] However, the support area of ​​the columnar spacers is limited, and the columnar spacers are prone to misalignment and movement when the TFT LCD is pressed, resulting in a change in the thickness of the liquid crystal cell, resulting in TOUCH MURA (non-uniform brightness of the liquid crystal display device causing various defects in the TFT LCD) Phenomenon) is bad; when the TFT LCD is under pressure, the columnar spacer will move and dislocate, which will also lead to poor light leakage and contrast reduction of the TFT LCD
