Array substrate, display panel, display device and method for manufacturing array substrate

Abstract

An array substrate (100), a display panel (200), a display device (300), and a manufacturing method for the array substrate (100), the array substrate (100) comprising: a first substrate (12) and a data line (64), the data line (64) being arranged on the first substrate (12); an auxiliary electrode (60) arranged on the first substrate (12), the auxiliary electrode (60) being used for electrical connection to a colour film substrate (140), and the vertical projection of the auxiliary electrode (60) on the first substrate (12) not intersecting the data line (64); an insulation layer (90) arranged on the surface of the side of the first substrate (12) furthest from the auxiliary electrode (60), the insulation layer (90) being provided with an open hole (40); and a light shielding electrode (30), comprising a main section (34) and a protruding section (32) interconnected into one, the main section (34) being positioned on the side of the first substrate (12) furthest from the data line (64), the vertical projection of the main section (34) on the first substrate (12) covering the data line (64), and the protruding section (32) being positioned on the insulation layer (90), the protruding section (32) penetrating through the open hole (40) and being in contact with the auxiliary electrode (60). The advantages are high product yield and saving production costs.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a display panel, a display device and a manufacturing method of the array substrate. Background technique [0002] The PSVA (Polmer Stabilized Vertically Aligned, polymer stabilized vertically aligned liquid crystal) mode liquid crystal display panel uses a vertical electric field in the vertical direction to drive the liquid crystal molecules vertically arranged on the glass substrate, thereby forming a polymer stabilized and vertically aligned liquid crystal. display panel. The liquid crystal display panel in this mode is in a black display state when no voltage is applied; after a certain voltage is applied, the liquid crystal molecules of the liquid crystal display panel fall to the horizontal direction, and the liquid crystal display panel in this mode is in a white display state. [0003] In the prior art, in order to avoid light leakage ...
