Abstract

The invention provides an array substrate and a display device, and belongs to the field of liquid crystal display. The array substrate comprises a plurality of grid lines, data lines and an array of a plurality of network unit grids formed by the grid lines and the data lines; each network unit grid comprises at least one thin film transistor and four sub-pixel electrodes in the same domain direction; the intersection points of the grid lines and the data lines serve as center points, and a pixel unit is formed by the four sub-pixel electrodes, adjacent to the center points, coming from the interiors of four different network unit grids with the adjacent centers and thin film transistors for controlling the four sub-pixel electrodes; the four sub-pixel electrodes in the pixel unit are different in domain direction, and are in mirror symmetry distribution in the upper direction, the lower direction, the left direction and the right direction. The uniquely-distributed sub-pixel electrode structure connected with the thin film transistors is driven by the thin film transistors, the wide visual angle effect is even and stable, and the image display quality is improved.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an array substrate and a display device. Background technique [0002] With the rapid development of liquid crystal display technology, people have higher and higher requirements for liquid crystal display. In order to achieve the purpose of wide viewing angle, there are more and more technologies used to realize pixel multi-domain design and mirror symmetry. [0003] For ADS, IPS, VA and other modes, such as figure 1 As shown, it is an array substrate provided in the prior art, which includes a network cell formed by crossing gate lines 1 and data lines 2, and the sub-pixel electrodes in the network cell have a double-domain structure, and the thin film transistor 4 drives the thin film transistor. Network cells (pixel units), so as to achieve the purpose of wide viewing angle. [0004] Among them, ADS is the core technology of planar electric field wide viewing angle - Adv...
