Abstract: A display panel includes a base substrate, and a pixel definition layer and pixels that are disposed on the base substrate. The pixel definition layer includes first pixel openings, second pixel openings and third pixel openings. The pixels are arranged in M rows and N columns. A pixel includes a first sub-pixel located at a first pixel opening, a second sub-pixel located at a second pixel opening, and a third sub-pixel located at a third pixel opening. The first sub-pixel, the second sub-pixel and the third sub-pixel emit light of different colors and are sequentially arranged in a third direction. In the third direction, two adjacent sub-pixels that emit light of a same color are separated by at least two sub-pixels that emit light of another colors, and the at least two sub-pixels emit light of colors that are different from each other.
