Abstract

The invention provides a TFT array substrate, a display panel and a display device. The TFT array substrate comprises a base plate, a shade conducting layer, and a common electrode; the shade conducting layer is arranged on the base plate; the common electrode is arranged above the shade conducting layer. The base plate comprises a plurality of pixels. The shade conducting layer comprises shade elements, a plurality of first and second common electrode lines; the shade elements are used for shading TFT grooves in each pixel; the first common electrode lines extend in a first direction; the second common electrode lines extend in a second direction; at least one of the first and second common electrode lines is electrically connected with the common electrode; the second and first common electrode lines intersect in a mesh structure; projections of the first and second common electrode lines, perpendicular to the base plate, cover gaps among the pixels. The first and second common electrode lines forming in the mesh structure are electrically connected with the common electrode, so that voltages of the common electrode are more balanced and the problems of crosstalk and flicker are improved.

Description

technical field [0001] The present invention relates to the technical field of displays, and more specifically, to a TFT (Thin Film Transistor, Thin Film Field Effect Transistor) array substrate, a display panel and a display device. Background technique [0002] Liquid crystal display panel has many advantages such as low radiation, low power consumption, light and thin volume, etc. It is the most mainstream display panel in the field of display technology at present. Wide viewing angle is a major trend in the development of liquid crystal display panel. According to the different arrangements of liquid crystal molecules, wide viewing angle liquid crystal display panels can be divided into IPS (In-Plane Switching, in-plane switching) type, FFS (Fringe Field Switching, fringe field switching) type, VA (Vertical Alignment, vertical alignment) type . Among them, the FFS liquid crystal display panel has the advantages of high light transmittance, wide viewing angle, small cros...
