Abstract

A liquid crystal display panel comprises an array substrate (1), a passivation layer (2) positioned above the array substrate (1) and a planarization layer (3) positioned above the passivation layer (2). The planarization layer (3) is provided with multiple first common electrodes. A light-shielding second common electrode (14) is provided in the array substrate (1). The second common electrode (14) is positioned at an edge of an active area region (AA region) of the liquid crystal display panel and extends to the inside and / or outside of the active area region (AA region). The outermost first common electrode (5) among the multiple first common electrodes is electrically connected to the second common electrode (14). The liquid crystal display panel can solve the problem of light leaking from an edge of an active area region thereof.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel. Background technique [0002] BPS (Black photo spacer, black photoresist spacer material) technology is a technology in LCD (Liquid Crystal Display, liquid crystal display) technology that combines two processes of BM (black matrix) and PS (gap control) into one process. Putting the BPS process on the side of the array substrate can realize the common use of flat screens and curved screens. The BPS process is placed on the side of the array substrate, which is an important design point for the design of the AA area (active area, effective display area) of the display panel and the periphery of the AA area. [0003] The design of the normal BPS technology at the junction of the perimeter and the AA area is as follows: figure 1 as shown, figure 1 Among them, 11' is the glass substrate, 12' is the gate insulating layer, 13' is the data line, 14' i...
