Abstract: The present disclosure provides various arrangements of a pixel defining layer. The pixel defining layer includes first and second sub-defining layers sequentially and laminatedly disposed on a base substrate. An orthographic projection of the second sub-defining layer less closer to the base substrate on the base substrate is located within an orthographic projection of the first sub-defining layer closer to the base substrate on the base substrate. A surface of each of the first and second sub-defining layers parallel to a surface of the base substrate is a lyophobic surface, a side surface of each of the first and second sub-defining layers is a lyophilic surface.

Abstract: An array substrate includes a substrate, first pixel defining layers, second pixel defining layers, and spacer assemblies. The first pixel defining layers and the second pixel defining layers jointly define pixel regions. The first pixel defining layer is used for separating two columns of pixel regions adjacent in a first direction. The height of the second pixel defining layer is lower than the height of the first pixel defining layer. The spacer assemblies are disposed on the substrate and in one-to-one correspondence with the columns of pixel regions. Spacers in each spacer assembly extend along a second direction. The height of each spacer is used for matching the properties of the first pixel defining layers, such that pixel ink can be uniformly filled between two adjacent first pixel defining layers.
