Abstract

The invention provides a thin film transistor array substrate. The thin film transistor array substrate comprises a substrate which includes a first surface and a second surface which are arranged oppositely, a transparent electric conduction layer which is corresponding to the first surface of the substrate and comprises at least one hole, an insulating layer arranged on the transparent electric conduction layer, and a pixel electrode which is arranged on the insulating layer and is corresponding to the hole of the transparent electric conduction layer.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a thin film transistor array. Background technique [0002] A liquid crystal display device with fringe field switching (Fringe Field Switching, FFS) technology usually generates a fringe electric field through the joint action of the pixel electrode and the common electrode, so that the joint action between the pixel electrode and the bottom electrode generates a fringe electric field, so that between the pixel electrodes and The liquid crystal molecules directly above the pixel electrodes can rotate in a direction parallel to the substrate, thereby increasing the light transmittance of the liquid crystal layer. It can be seen that the FFS technology solves the problems of low light transmittance and high power consumption of the conventional InPanel Switching display panel. [0003] In the FFS liquid crystal display device, the pixel electrode needs to be insulated and in...
