Claim 15:
16. An array substrate, comprising:
a base substrate;
a driving circuit structure on the base substrate,
a planarization layer and a plurality of electrode structures successively located on a side, facing away from the base substrate, of the driving circuit structure;
insulation structures in gap areas between adjacent electrode structures among the plurality of electrode structures; wherein a thickness of the insulation structures is not smaller than a thickness of the electrode structures; and
pixel defining structures on a side, facing away from the base substrate, of the insulation structures; wherein an orthographic projection of the pixel defining structures on the base substrate at least completely covers the insulation structures;
wherein the pixel defining structures comprise opening areas, the opening areas are disposed in one-to-one correspondence with the electrode structures, and the opening areas at least expose parts of the electrode structures;
the thickness of the insulation structures is larger than the thickness of the electrode structures;
the pixel defining structures comprise:
first structure units extending in a row direction and arranged successively in a column direction; and
second structure units extending in the column direction and arranged successively in the row direction;
wherein each of the opening areas is enclosed by parts of two of the first structure units and parts of two of the second structure units;
center axes of the parts of the two first structure units and center axes of the parts of the two second structure units are connected to form a closed graph enclosing the each of the opening areas; and
in a direction, pointing from the each of the opening areas to the center axes, a distance between an upper surface of the pixel defining structure and the base substrate increases successively.
