Abstract
Provided in the present disclosure are a display substrate, a preparation method therefor, and a display apparatus. The display substrate includes a substrate, a light-emitting structure layer disposed on the substrate, and a encapsulation structure layer disposed on the light-emitting structure layer; the encapsulation structure layer includes a encapsulation layer and at least one transition layer; a side of a transition layer adjacent to the substrate makes contact with a first side film layer, and a side of a transition layer away from the substrate makes contact with a second side film layer; the adhesion of the at least one transition layers is greater than that of one film layer among the first side film layer and the second side film layer, and less than that of the other film layer among the first side film layer and the second side film layer.
