Title: PSVA-TYPE LIQUID CRYSTAL DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Abstract:
A PSVA-type liquid crystal display panel and a manufacturing method therefor. The PSVA-type liquid crystal display panel comprises a patterned passivation layer (22), the upper surface of the passivation layer (22) comprising grooves (221) of various depths, said layer being capable of compensating, to a certain extent, the uniformity of the transmittance, and being conducive to the improvement of the large viewing angle characteristic of the PSVA-type liquid crystal display panel. The manufacturing method for the PSVA-type liquid crystal display panel uses a multi-tone mask process, utilizing a multi-tone mask to manufacture, by means of a photolithography process, on the passivation layer (22) grooves (221) of various depths and vias (223) at the same time, reducing the production cost and improving production efficiency.
