Display panel and display device

Abstract

The invention discloses a display panel and a display device, wherein the display panel comprises a color film substrate and an array substrate arranged opposite to the color film substrate. A gap isformed between the color film substrate and the array substrate, the gap is filled with liquid crystal, the color film substrate defines a plurality of pixel areas, the color film substrate comprisesa transparent photoresist, the transparent photoresist is provided with a first photoresist layer and second photoresist layer corresponding to each pixel area, the first photoresist layer and the second photoresist layer divide the pixel areas into a first domain area and a second domain area, and the gap in the first domain area is larger than the gap in the second domain area. According to theinvention, liquid crystal gaps of different domain areas are formed in each pixel area through different photoresist layer thicknesses, so that the problem of large visual color cast is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is usually composed of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, and a liquid crystal layer (Liquid Crystal Layer, LC Layer) arranged between the two substrates. ) constitutes. The working principle of the liquid crystal display is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on the two glass substrates, and refract the light from the backlight module to produce a picture. [0003] As far as LCDs currently on the market are concerned, they can be divided into three types, namely twisted nematic (Twisted Nematic, TN) or super twisted nematic (Super Twisted Nematic, STN) type, in-plane switching (In-Plane Switching, IPS ...

AI Technical Summary

Problems solved by technology

However, since the VA-type liquid crystal display panel uses vertically rotating liquid crystals, the difference in birefringence of liquid crystal molecules is relatively large, resulting in serious color shift problems at large viewing angles.

In other words, in the same sub-pixel of the LCD panel, the gap between the two glass substrates (cell gap) is the same, and the tilting state of the liquid crystal molecules after being subjected to voltage is also the same, so that the color difference seen from different angles of the VA-type LCD panel is different. Larger, resulting in picture distortion, thereby reducing the user's viewing effect for large viewing angles, and also reducing the reliability of the panel manufacturer's product quality

[0004] Therefore, it is necessary to provide a display panel and a display device to solve the problem of color shift under large viewing angles in the prior art
