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.
