Array substrate and liquid crystal display panel

Abstract

The invention provides an array substrate and a liquid crystal display panel. The array substrate comprises a substrate body, a thin film transistor layer located on the substrate body and a pixel electrode located on the thin film transistor layer. The array substrate comprises a plurality of sub-pixel areas, and each sub-pixel area comprises a main area and an auxiliary area. The pixel electrodes are arranged corresponding to the main area and the auxiliary area, and each pixel electrode comprises a first main electrode and a first branch electrode which correspond to the main area, and a second main electrode and a second branch electrode which correspond to the auxiliary area; the first branch electrode is electrically connected with the first main electrode at a first preset angle;thesecond branch electrode is electrically connected with the second main electrode at a second preset angle;and the first preset angle is different from the second preset angle. By controlling the angle of the pixel electrode, the number of thin film transistors in the prior art is reduced, the pixel aperture opening ratio and transmittance are increased, and meanwhile the wide viewing angle effectof the liquid crystal display panel is achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] A liquid crystal display panel is usually composed of a color filter substrate, a thin film transistor array substrate, and a liquid crystal layer disposed between the two substrates, including twisted nematic (TN) mode, electronically controlled birefringence (ECB) mode, vertical alignment (VA) Among them, the VA mode is a common display mode with the advantages of high contrast, wide viewing angle, and no need for frictional alignment. However, since the vertically rotating liquid crystal is used in the VA mode, the difference in birefringence of the liquid crystal molecules is relatively large, resulting in serious color shift problems at large viewing angles. [0003] At present, in order to improve the viewing angle performance of the panel, the PSVA pixel design of 3T-8domain (8...

Problems solved by technology

However, since the VA mode uses vertically rotating liquid crystals, the difference in birefringence of liquid crystal molecules is relatively large, resulting in serious color shift problems at large viewing angles.

[0003] At present, in order to improve the viewing angle performance of the panel, the PSVA pixel design of 3T-8domain (8 domains and 3 transistors) is usually used. However, in 3T-8domain (8 domains and 3 transistors), a display panel with a VA pixel structure driven by 3 TFTs is required. , although this design can increase the viewing angle, it will lose the aperture ratio, and at the same time require the backlight to provide higher brightness, resulting in an increase in power consumption
