Abstract

The invention discloses an array substrate, a display panel, a display device and a manufacturing method of the array substrate; wherein the array substrate comprises a transparent substrate body, and a photosensitive structure is arranged in a frame area of the transparent substrate body; the photosensitive structure comprises a first conductor layer, a first insulating layer and a photosensitive material layer which are sequentially arranged on the transparent substrate; the first conductor layer is provided with a through hole, and the through hole is located in an orthographic projection area of the photosensitive material layer on the first conductor layer; one side of the photosensitive material layer is conducted with the active layer of the array substrate through the second conductor layer, and the other side of the photosensitive material layer is conducted with the back-plated conductive film of the transparent color film substrate through the third conductor layer. According to the array substrate, a residual charge release path from in-plane to out-of-plane is constructed, so that in-plane residual charges can be effectively dissipated, and the problems of picture jitter and drifting of a liquid crystal display panel caused by the in-plane residual charges are solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel, a display device and a manufacturing method of the array substrate. Background technique [0002] At present, liquid crystal panels, especially oxide FFS products based on fringe field switching technology, are prone to residual charge accumulation due to the low cut-off voltage Ioff; the charge mainly exists inside the panel, and the occurrence time and position of the residual charge cannot be monitored. The existence of residual charges will cause image jitter and Flicker drift problems in the liquid crystal display panel. For the problem of residual charge in the plane, the main solution currently used is to bake the panel at high temperature, but the effect of charge dissipation is not good; there are also related technologies: forming a resist layer on the substrate, and forming a resist layer on the resist layer A method of co...
