Abstract: A display substrate includes a first electrode layer, a pixel define layer, an organic light-emitting layer, a second electrode layer and a first encapsulation layer which are sequentially disposed away from a base substrate. The pixel define layer has a plurality of openings, at least one of which exposes the first electrode layer. The pixel define layer has a first climbing part and a second climbing part close to the edge of at least one opening, the distance from a surface of the second climbing part away from the base substrate to the base substrate is greater than the distance from a surface of the first climbing part away from the base substrate to the base substrate, and the slope angle of the first climbing part is different from that of the second climbing part.
