Abstract: A pixel defining structure includes a first sub-pixel defining structure surrounding a first sub-pixel region configured to form a first sub-pixel having a first color. The first sub-pixel defining structure includes a lyophilic portion one the bottom side of the first sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The pixel defining structure includes a second sub-pixel defining structure surrounding a second sub-pixel region configured to form a second sub-pixel having a second color. The second sub-pixel defining structure includes a lyophilic portion one the bottom side of the second sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The second color is different from the first color. Thicknesses of the lyophilic portion of the first sub-pixel defining structure and the lyophilic portion of the second sub-pixel defining structure are different.

Abstract: The present disclosure discloses a pixel defining layer and a manufacturing method thereof, an array substrate and a display device, and belongs to the field of display technology. The pixel defining layer includes a plurality of pixel defining structures arranged in an array, wherein the pixel defining structure includes a first bottom surface and a second bottom surface opposite each other, and a side surface located between the first bottom surface and the second bottom surface. Since the side surface is non-planar, the structure between the side surface and the bottom surface close to the base substrate constitutes a capillary structure. During the inkjet printing process, the solution in which the organic light emitting material is dissolved can spread more evenly under the attraction of the capillary structure.
