Abstract

Provided is an array substrate. Each sub pixel (10) in the array substrate comprises a thin film control transistor (T1) and a pixel electrode (40) electrically connected to the thin film control transistor (T1). The pixel electrode (40) comprises a primary zone pixel electrode (41) and a secondary zone pixel electrode (42) which are spaced apart, and a first connecting electrode (43) electrically connected to the primary zone pixel electrode (41) and the secondary zone pixel electrode (42). Both the primary zone pixel electrode (41) and the secondary zone pixel electrode (42) are slit electrodes in the shape of eight-pointed asterisks; the width of primary zone branch electrodes (412) of the primary zone pixel electrode (41) is less than that of secondary zone branch electrodes (422) of the secondary zone pixel electrode (42); and the width of primary zone slits (413) of the primary zone pixel electrode (41) is less than that of secondary zone slits (423) of the secondary zone pixel electrode (42). The color cast can be improved through the structural difference between the primary zone pixel electrode (41) and the secondary zone pixel electrode (42), and at the same time, the number of TFTs in the sub pixels (10) is reduced, the opening rate of the pixels is increased, and the difficulty of optimal common voltage balance regulation and the control of primary zones and secondary zones 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...
