Claim 17:
18. The method according to claim 15, before processing the second flexible base substrate layer, the method further comprises: forming a thin film transistor layer on a side of the second flexible base substrate layer away from the first buffer layer, forming a third via hole having a position corresponding to that of the first via hole on the thin film transistor layer, wherein
processing the second flexible base substrate layer to make the first via hole penetrate through the second flexible base substrate layer comprises: processing the second flexible base substrate layer to make the first via hole and the third via hole communicated with each other and penetrate through the first flexible base substrate layer and the second flexible base substrate layer; and sequentially forming an organic light emitting layer and an encapsulation thin film layer on the thin film transistor layer.
