The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a bottom plate, wherein a subzone common electrode, a compensation electrode and a subzone pixel electrode are overlaid on the bottom plate in sequence; the compensation electrode and the subzone common electrode are in insulated arrangement, and the compensation electrode is electrically connected with the subzone pixel electrode through a through hole; the projection area of the compensation electrode on the bottom plate is not greater than the projection area of the subzone commonelectrode on the bottom plate; at least parts of the projection area of the subzone common electrode on the bottom plate are overlapped with the projection area of the subzone pixel electrode on thebottom plate; and the projection are of the compensation electrode on the bottom plate and the projection area of the subzone pixel electrode on the bottom plate are not mutually overlapped. Accordingto the array substrate, liquid crystal alignment ability can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a display panel and a display device. Background technique [0002] In order to increase the viewing angle of liquid crystal displays, the existing technology usually adopts multi-domain technology, which divides a sub-pixel into multiple regions, and makes the liquid crystal in each region fall to different directions after voltage is applied. , so that the effects seen in all directions tend to be average and consistent. In order to improve visual chromatic aberration or visual color shift, in the prior art, a sub-pixel is divided into a main area and a sub-area, an independent main-area pixel electrode is set in the main area, and an independent sub-area pixel electrode is set in the sub-area, Both the pixel electrodes in the main area and the pixel electrodes in the sub area use rice-shaped slit electrodes to realize 8-domain display.

AI Technical Summary

Problems solved by technology

Excessive TFT (Thin Film Transistor, thin film transistor) will lead to a decrease in the aperture ratio of the pixel itself, and due to the use of charge sharing technology, the pixel voltage between the main area and the sub area will be different, which will increase the pixel voltage between the main area and the sub area. The best common voltage (best V com ) the difficulty of balancing regulation

With the increase in the number of TFTs and the increase in multi-domains, the space is very large. In order to effectively use the design space, the line spacing will be reduced to a small size, resulting in an overlapping area between the supplementary electrode and the pixel electrode, which will have a shielding effect on the common electrode signal. Poor liquid crystal alignment is prone to occur
