Abstract

An array substrate, a display panel, and a display device are provided. The array substrate comprises a plurality of pixel regions in an array along intersected first and second directions. The pixel region includes at least three subpixel regions. At least one subpixel region serves as an adjustment-subpixel region. The subpixel region has a first electrode including at least two parallel first straight portions. Second straight portions and first connecting portions are connected to first and second ends of the first straight portions, respectively. The first electrode corresponding to the adjustment-subpixel region serves as an adjustment electrode. An opening is configured at an end between the at least two adjacent second straight portions corresponding to the adjustment electrode. An angle between extending direction of the first straight portion and the second direction is less than an angle between extending direction of the second straight portion and the second direction.
