1. A display substrate, comprising:
a flexible base substrate comprising at least one stretch display region, wherein the stretch display region comprises multiple pixel island regions spaced apart from each other, multiple hole regions, and a connection bridge region located between a pixel island region and a hole region; wherein at least one hole region is provided with one or more first through holes penetrating the flexible base substrate;
a first filling layer located in the hole region and filled in a first through hole; and
an encapsulation layer located on a side of the first filling layer away from the flexible base substrate, wherein an orthographic projection of the encapsulation layer on the flexible base substrate is partially overlapped with or is not overlapped with the first filling layer.
