Claim 0:
1. An array substrate, comprising:
a base substrate;
a plurality of first electrodes arranged on the base substrate, wherein the plurality of first electrodes are spaced apart from each other;
a plurality of first pixel defining portions arranged on the base substrate;
a plurality of second pixel defining portions arranged on the base substrate, wherein the plurality of first pixel defining portions and the plurality of second pixel defining portions jointly define a plurality of pixel openings including at least a first pixel opening and a second pixel opening, and orthographic projections of the plurality of pixel openings on the base substrate are respectively located within orthographic projections of the plurality of first electrodes on the base substrate; and
a light emitting functional layer arranged on the base substrate, wherein the light emitting functional layer comprises at least 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 is located in the first pixel opening, and at least a part of the second light emitting portion is located in the second pixel opening;
wherein at least one of the plurality of first pixel defining portions is located between a first pixel opening and a second pixel opening that are adjacent in a first direction, and at least one of the plurality of second pixel defining portions is located between two first pixel openings that are adjacent in the first direction or is located between two second pixel openings that are adjacent in the first direction;
wherein an orthographic projection of a combination of two adjacent pixel openings separated by the second pixel defining portion on the base substrate has a first size in the first direction and a second size in a second direction different from the first direction, and a ratio of the first size to the second size is within a range of 0.8 to 1.2;
wherein the base substrate has a first surface facing the plurality of first electrodes, the first pixel defining portion has a first height in a direction perpendicular to the first surface, the second pixel defining portion has a second height in the direction perpendicular to the first surface, and the first height is greater than the second height;
wherein the array substrate further comprises a plurality of third pixel defining portions, wherein at least one of the third pixel defining portions is located between two first pixel openings that are adjacent in a third direction or is located between two second pixel openings that are adjacent in the third direction, the third direction is different from the first direction and the second direction; and
wherein the third pixel defining portion has a third height in the direction perpendicular to the first surface, and the first height is greater than the third height.
