Abstract
In one embodiment, there is provided a display substrate including: a base substrate; a plurality of pixels on the base substrate; and a pixel definition layer on the base substrate, defining the pixels and separating the pixels from one another. Each of the pixels includes: a first electrode assembly, a light-emitting function layer and a second electrode arranged sequentially in a direction away from the base substrate, and the second electrodes of the pixels form a common electrode layer extending over the pixel definition layer. In each of the pixels, a distance between a surface of the pixel definition layer away from the base substrate and a surface of the light-emitting function layer away from the base substrate in the direction away from the base substrate is less than or equal to a preset threshold that is in a range of about 0 Å to about 300 Å.
