Abstract

Provided is a display substrate having a polygonal encapsulation region with a plurality of edges and a periphery region surrounding the encapsulation region. The display substrate includes a base substrate, and a partition structure within the periphery region on a side of the base substrate. The partition structure includes a plurality of isolation dams, arranged at intervals along a direction away from the encapsulation region, outside each edge of the encapsulation region. The plurality of edges include a first edge and a second edge, and a plurality of first isolation dams outside the first edge are not in connection with, and have more dams than, a plurality of second isolation dams outside the second edge.
