Liquid crystal display panel

Abstract

The invention provides a liquid crystal display panel. A groove (V) penetrating a black matrix (BM) is dug in the black matrix (BM) positioned in a non-display area (NA), so that the black matrix (BM)can be stopped from conducting static electricity from the non-display area (NA) to a display area (AA), and anti-static capacity is enhanced. A light shield layer (4) is arranged on a thin film transistor array substrate (1), the width of the light shield layer (4) is larger than that of the groove (V), so that the light shield layer (4) shields backlight irradiating the groove (V), light leakage of the groove (V) of the black matrix (BM) can be effectively avoided, bright lines of the non-display area (NA) of the liquid crystal display panel are prevented, and the display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, smart phone, digital camera, computer screen or notebook computer screen, etc. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. [0004] Please also see figure 1 and figure 2 A conventional liquid crystal display panel includes a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate) 100 and a color filter substrate (Color Filter, CF) 200 disposed opposite to each other, and a liquid crystal layer (Liquid Crystal) disposed between the ...

AI Technical Summary

Problems solved by technology

[0006] like figure 1 and figure 2 As shown, after the red photoresist R' fills the trench V' of the black matrix BM', it will form a lift on both sides, and then the red photoresist R' cannot be completely covered when the blue photoresist B' is filled. , so that there is a gap K' between the two sides of the red photoresist R' and the blue photoresist B', and there is only the red photoresist R' in the gap K', which has a high transmittance and is easy to leak light. After the module is turned on, a red bright line L will be formed in the non-display area NA' of the LCD panel, which will affect the display quality of the LCD panel
