Abstract

An array substrate, including: a plurality of first pixel defining portions and a plurality of second pixel defining portions arranged on a base substrate and jointly define a plurality of pixel openings; and a light emitting functional layer arranged on the base substrate and includes a first light emitting portion and a second light emitting portion that emit different colors of light, at least a part of the first light emitting portion and the second light emitting portion is respectively located in a first pixel opening and a second pixel opening. An orthographic projection of a combination of two adjacent pixel openings separated by the second pixel defining portion on a base substrate has a first size in a first direction and a second size in a second direction, and a ratio of the first size to the second size is within a range of 0.8 to 1.2.
