Abstract

A display substrate including: a base substrate with a display region, an encapsulation region and an edge region on a periphery of the encapsulation region, the edge region includes a bonding region on at least one side of the base substrate; a plurality of stacked inorganic film layers on a side of the base substrate; a plurality of first grooves, at the edge region, spaced apart from each other in a direction distal from the encapsulation region, and extending along a periphery of the base substrate, at least one of the plurality of first groove runs through at least one inorganic film layer of the plurality of inorganic film layers, and a distance between each first groove and the display region is larger than that between each first groove and an edge of the base substrate; and an organic layer.
