Abstract
The present application discloses a display substrate having a base substrate and a pixel definition layer for defining a plurality of subpixel regions on the base substrate. The pixel definition layer has a first side and a second side opposite to each other, the second side being on a side of the first side distal to the base substrate. The pixel definition layer has a first cross-section along a plane substantially parallel to the base substrate, the first cross-section being between the first side and the second side. An orthographic projection of the first cross-section on the base substrate substantially covers orthographic projections of the first side and the second side on the base substrate.
