Title:
ARRAY SUBSTRATE AND PREPARATION METHOD THEREFOR, AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2018/090496
Kind Code:
A1
Abstract:
An array substrate and a preparation method therefor, and a liquid crystal display panel, relating to the technical field of display. Compared with the prior art, no leakage path is generated, such that the display uniformity can be improved. The array substrate comprises a plurality of sub-pixels (10), wherein each of the sub-pixels (10) comprises a first thin film transistor (20), a pixel electrode (40) and a common electrode (50) arranged on a substrate; the pixel electrode (40) is electrically connected to a drain electrode (301) of the first thin film transistor (30) through a via hole (60); each of the sub-pixels (10) further comprises an auxiliary electrode (70) disposed at the via hole (60); the auxiliary electrode (70) is arranged between the pixel electrode (40) and the drain electrode (301) of the first thin film transistor (30); the pixel electrode (40) is electrically connected to the drain electrode (301) of the first thin film transistor (30) by means of the auxiliary electrode (70); the common electrode (50) is arranged at one side, far away from the substrate (20), of the pixel electrode (40); and at the via hole (60), an orthogonal projection of the common electrode (50) on the substrate (20) does not overlap with an orthographic projection of the pixel electrode (40) on the substrate (20).
