Claim 14:
15. A method for manufacturing a flexible substrate, comprising:
sequentially forming a first flexible base substrate layer and a first buffer layer on a rigid underlaying substrate, and forming a first via hole on the first buffer layer;
processing the first flexible base substrate layer to make the first via hole penetrate through the first flexible base substrate layer, wherein an orthographic projection of a surface of the first buffer layer facing the first flexible base substrate layer on the rigid underlaying substrate is larger than an orthographic projection of a surface of the first flexible base substrate layer facing the first buffer layer on the rigid underlaying substrate;
forming a second flexible base substrate layer on a side of the first buffer layer away from the first flexible base substrate layer;
processing the second flexible base substrate layer to make the first via hole penetrate through the second flexible base substrate layer; and
lifting off the rigid underlaying substrate to obtain the flexible substrate.
