Problems solved by technology

Under different viewing angles, due to the averaging effect of the deflection of the liquid crystal 7, the brightness difference of the liquid crystal display is reduced, and the chromatic aberration is improved to a certain extent, but this technical solution can only improve the chromatic aberration to a certain extent, and the chromatic aberration phenomenon of the liquid crystal display still exists. For further improvement, for example, the strip-shaped pixel electrode of a sub-pixel has four kinds of inclination angles, so that when the liquid crystal display is working, the liquid crystal 7 in each sub-pixel has four kinds of deflection angles under the drive of the electric field, which can be greatly improved. Improve the chromatic aberration phenomenon of liquid crystal display, but due to the limitation of the process, the formation of strip pixel electrodes with four inclined angles in one sub-pixel will greatly affect the transmittance of liquid crystal display

Abstract

The invention provides a pixel structure, an array substrate and a display device, and belongs to the technical field of displaying. The pixel structure comprises multiple sub pixel units driven by a same grid line and a same data line. Each pixel unit is composed of two or more sub pixels. Each sub pixel unit is divided into N display areas. In a power-up state, electric fields of display areas are different, so that the N-domain display of the sub pixel units can be achieved. According to the technical scheme, on the premise of guaranteeing the transmittance of a liquid crystal display device, the color difference phenomenon of the liquid crystal display device is improved.
