Claim 15:
16. The method according to claim 15, wherein when the first flexible base substrate layer is processed, the method further enables that a junction surface of the first via hole and the first flexible base substrate layer is a slope surface and an orthographic projection of a surface of the first flexible base substrate layer facing the rigid underlaying substrate on the rigid underlaying substrate is larger than an orthographic projection of a surface of the first flexible base substrate layer away from the rigid underlaying substrate on the rigid underlaying substrate; and
when the second flexible base substrate layer is processed, the method further enables that a junction surface of the first via hole and the second flexible base substrate layer is a slope surface and an orthographic projection of a surface of the second flexible base substrate layer facing the first buffer layer on the rigid underlaying substrate is larger than an orthographic projection of a surface the second flexible base substrate layer away from the first buffer layer on the rigid underlaying substrate.
