Claim 12:
13. A flexible display substrate, comprising a flexible substrate, a thin film transistor layer, an organic light emitting layer, and an encapsulation thin film layer which are sequentially arranged from bottom to top, wherein the flexible substrate comprises a plurality of island regions spaced apart and a plurality of bridge regions connected between different island regions, and has a plurality of openings in regions which are neither the island regions nor the bridge regions, a plurality of layer structures are arranged on each island region, the layer structures comprise a first flexible base substrate layer, a first buffer layer, and a second flexible base substrate layer which are sequentially stacked from bottom to top, and an orthographic projection of a surface of the first buffer layer facing the first flexible base substrate layer on the first flexible base substrate layer is larger than an orthographic projection of a surface of the first flexible base substrate layer facing the first buffer layer on the first flexible base substrate layer.
