Claim 16:
17. A preparation method of a display substrate, comprising:
sequentially forming a first flexible substrate layer and a first connection layer on a rigid base substrate, wherein a first via is provided on the first connection layer;
processing the first flexible substrate layer to form a first groove corresponding to the first via, wherein the first via and the first groove are mutually communicated, and an orthographic projection of the first groove on the first flexible substrate layer comprises an orthographic projection of the first via on the first flexible substrate layer;
forming a second flexible substrate layer on a side of the first connection layer away from the first flexible substrate layer;
sequentially forming a second barrier layer, a driving structure layer, a light-emitting element, and an encapsulation layer; and
peeling off the rigid base substrate to obtain the display substrate.
