Abstract

The invention provides an array substrate. Each sub-pixel in the array substrate comprises a control thin film transistor and a pixel electrode electrically connected with the control thin film transistor. Each pixel electrode comprises a main region pixel electrode, an auxiliary region pixel electrode and a first connecting electrode, wherein the main region pixel electrode and the auxiliary region pixel electrode are arranged in a spaced mode, and the first connecting electrode is electrically connected with the main region pixel electrode and the auxiliary region pixel electrode. The main region pixel electrodes and the auxiliary region pixel electrodes are slit electrodes shaped like a Chinese character 'mi'. The width of main region branch electrodes of the main region pixel electrodes is smaller than that of auxiliary region branch electrodes of the auxiliary region pixel electrodes, and the width of main region slits of the main region pixel electrodes is smaller than that of auxiliary region slits of the auxiliary region pixel electrodes. Color cast can be relieved through the structural difference of the main region pixel electrodes and the auxiliary region pixel electrodes, the number of TFTs in the sub-pixels is reduced, the opening rate of the pixels is increased, and the difficulty of optimal common voltage balance regulation and control of main regions and auxiliary regions is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is one of the most widely used flat panel displays at present, and a liquid crystal panel is a core component of the liquid crystal display. A liquid crystal panel is generally composed of a color filter substrate (ColorFilter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFTArray Substrate), and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. Generally, pixel electrodes and common electrodes are respectively arranged on the array substrate and the color filter substrate. When a voltage is applied to the pixel electrode and the common electrode, an electric field will be generated in the liquid crystal layer, which determines the orientation of the liquid crystal molecules, thereby adjusting the...
