Claim 8:
9. A method for manufacturing a display substrate, comprising:
providing a base substrate, wherein the base substrate is provided with an encapsulation region and an edge region on a periphery of the encapsulation region, the encapsulation region comprises a display region and a peripheral region surrounding the display region, and the edge region comprises a bonding region on at least one side of the base substrate;
forming a plurality of stacked inorganic film layers on a side of the base substrate from an inorganic material;
forming a plurality of first grooves which are spaced apart from each other and extend along a periphery of the base substrate on the edge region in a direction distal from the encapsulation region, wherein the plurality of first grooves run through at least one inorganic film layer of the plurality of stacked inorganic film layers, and orthographic projections of the plurality of first grooves on the base substrate have a non-overlapping region with the bonding region, and distances between the plurality of first grooves and the display region are larger than distances between the plurality of first grooves and an edge of the base substrate; and
forming an organic layer covering the plurality of first grooves from an organic material; and
wherein the display substrate is display substrate according to claim 1.
