1. A displaying base plate, comprising an opening area and an isolation area surrounding the opening area, wherein:
the isolation area comprises a first flexible substrate and at least one isolation slot disposed on one side of the first flexible substrate, the isolation slot being formed by a first inorganic film layer, an organic film layer and a second inorganic film layer that are stacked;
the first inorganic film layer is disposed close to the first flexible substrate, and the first inorganic film layer is provided with a first surface facing the opening area;
the organic film layer is disposed on one side of the first inorganic film layer that is away from the first flexible substrate, and the organic film layer is provided with a second surface facing the opening area;
the second inorganic film layer is disposed on one side of the organic film layer that is away from the first flexible substrate, and the second inorganic film layer is provided with a third surface facing the opening area;
the second surface is retracted with respect to the first surface and the third surface in a direction away from the opening area, and a surface of the first inorganic film layer that faces the second inorganic film layer and the second surface form the isolation slot;
the at least one isolation slot comprises a first isolation slot, the first inorganic film layer forming the first isolation slot comprises a first barrier layer, and the organic film layer forming the first isolation slot is a second flexible substrate; and
the at least one isolation slot comprises a second isolation slot, the organic film layer forming the second isolation slot is a first organic functional layer, and the first organic functional layer comprises at least one of: a planarization layer, a pixel definition layer disposed on one side of the planarization layer that is away from the first flexible substrate, and a supporting layer disposed on one side of the pixel definition layer that is away from the first flexible substrate.
