Problems solved by technology

[0002] In the current display field, the pixel design of FFS products is divided into two modes: horizontal domain and vertical domain. The contrast is slightly worse; while the cross-domain pixel design avoids this risk in the rubbing process, the PS station is located on the Gate line, the rubbing smear is not in the pixel area, there is no light leakage, and the brightness of the black state is low, so the contrast is greatly improved; However, although horizontal domain pixel design products have an advantage in contrast, when the display is parallel to the rubbing direction at low gray levels, there will be irregular fine lines on the full screen, that is, display mura (bad fine lines). Principle analysis: when rubbing When the angle and the angle of the polarizer are offset, the brightness of different domain directions will be different, and the pixel domain direction is the same, and the rubbing mura will be enlarged macroscopically, showing poor display

Abstract

The invention relates to the technical field of display, and discloses an array substrate, a liquid crystal display panel and a liquid crystal display device. The array substrate comprises multiple sub-pixels arranged in an array, wherein each sub-pixel comprises pixel electrodes; each pixel electrode comprises a electrode area with a domain direction; along a row direction, the domain directionsin the electrode areas of each two adjacent pixel electrodes are different; along a column direction, the domain directions in the electrode areas of each two adjacent pixel electrodes are different;or each pixel electrode comprises two electrode areas with different domain directions; along the row direction, the domain directions in adjacent electrode areas in each two adjacent pixel electrodesare different; along the column direction, the domain directions in adjacent electrode areas in each two adjacent pixel electrodes are different. The array substrate is applied to display products, so that the display effect of the display product is more uniform, the tiny mura display degree caused by rubbing direction deviation is weakened, and the display effect is effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] In the current display field, the pixel design of FFS products is divided into two modes: horizontal domain and vertical domain. The contrast is slightly worse; while the cross-domain pixel design avoids this risk in the rubbing process, the PS station is located on the Gate line, the rubbing smear is not in the pixel area, there is no light leakage, and the brightness of the black state is low, so the contrast is greatly improved; However, although horizontal domain pixel design products have an advantage in contrast, when the display is parallel to the rubbing direction at low gray levels, there will be irregular fine lines on the full screen, that is, display mura (bad fine lines). Principle analysis: when rubbing When there is a deviation between the angle a...
