Problems solved by technology

The reason for the appearance of the dark area is that the dislocation (Shift) of the upper and lower substrates of the liquid crystal display panel is the most serious here, and the dislocation distance is relatively large, which makes the black matrix (Black Matrix, BM) additional shading the most, resulting in the liquid crystal display panel here. The pixel penetration rate of the area is lower than that of other areas, which seriously affects the display effect

Abstract

The invention provides a liquid crystal display panel and a method for manufacturing the same. The method for manufacturing the liquid crystal display panel includes coating a photoresistance layer on a matrix; primarily exposing the photoresistance layer by the aid of first exposure energy and a first photomask to form spacing columns with first heights; secondarily exposing the photoresistance layer by the aid of second exposure energy and a second photomask to form spacing columns with second heights; removing unexposed portions of the photoresistance layer. The first photomask is provided with first transmittance zones corresponding to dark cluster zones. The second photomask is provided with second transmittance zones corresponding to dark cluster zones, and the second heights are larger than the first heights. Owing to the mode, the liquid crystal display panel and the method have the advantages that the efficiency of liquid crystal in the dark cluster zones can be enhanced, the penetration rates of pixels in the dark cluster zones can be guaranteed, and accordingly the dark cluster zones of the liquid crystal display panel can be reduced or eliminated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a manufacturing method thereof, so as to reduce or eliminate dark areas generated during curved surface display. Background technique [0002] Currently, liquid crystal display panels, such as TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display, thin film transistor liquid crystal display) panels, are prone to dark areas at the most serious bending (Bending) of the curved surface, and generally It is located near halfway from the center of the liquid crystal display panel to the left and right edges respectively. The reason for the appearance of the dark area is that the dislocation (Shift) of the upper and lower substrates of the liquid crystal display panel is the most serious here, and the dislocation distance is relatively large, which m...
