Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises multiple pixel units with 2*2 sub-pixel region matrixes. Each sub-pixel region comprises three sub-pixel electrodes, and a strip-shaped electrode in at least one sub-pixel electrode in the first sub-pixel region and a strip-shaped electrode in at least one sub-pixel electrode in the third sub-pixel region are in parallel with the first direction. A strip-shaped electrode in at least one sub-pixel electrode in the second sub-pixel region and a strip-shaped electrode in at least one sub-pixel electrode in the fourth sub-pixel region are in parallel with the second direction. The first direction and the second direction are intersected, the sub-pixel electrodes where the strip-shaped electrodes in parallel with the first direction are located and the sub-pixel electrodes where the strip-shaped electrodes in parallel with the second direction are located define a first region, and a sub-pixel electrode is arranged in the first region. According to the technical scheme, under the condition that the friction alignment direction deviates, or a polarizer deflects, the transverse striation problem can be effectively avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] Liquid crystal display devices have the advantages of thinness, low power consumption and low radiation, and are widely used in various fields. With the development of liquid crystal display technology, the display effect of liquid crystal display devices has been continuously improved. [0003] In the prior art liquid crystal display device, the strip electrodes in each row of pixel electrodes on the array substrate adopt a pseudo-double-domain structure arrangement, that is, for the strip electrodes in any two adjacent rows of pixel electrodes, one row The parallel direction of the strip-shaped electrodes is different from that of the other row of strip-shaped electrodes. In the process of making a liquid crystal display device, when the rubbing alignment direction deviates during...
