Claim 0:
1. A method for manufacturing an array substrate, comprising:
forming a pixel defining film on a base;
patterning the pixel defining film to form a pixel defining layer, wherein the pixel defining layer includes a plurality of defining strips extending in a first direction and a plurality of defining portions extending in a second direction, the first direction intersecting with the second direction; any two adjacent defining strips are provided with defining portions in the plurality of defining portions therebetween, the defining portions located between the two adjacent defining strips are spaced apart in the first direction, and a defining portion includes at least one first sub-portion and at least two second sub-portions, the at least one first sub-portion is connected to the two adjacent defining strips through the at least two second sub-portions, a thickness of a defining strip is greater than a thickness of a first sub-portion, and the thickness of the first sub-portion is greater than a thickness of a second sub-portion; wherein the defining portion includes one first sub-portion and two second sub-portions, the two second sub-portions are located on two opposite sides of the first sub-portion in the second direction, and a surface of the first sub-portion away from the side of the base is parallel to a plane where the second direction is located; and
forming a plurality of light-emitting layers, by using an inkjet printing process, on the base on which the pixel defining layer has been formed, wherein at least one portion of a light-emitting layer is disposed in a corresponding opening, and at least two light-emitting layers located between the two adjacent defining strips are connected to form a one-piece structure.
