Abstract
Provided is a display panel, comprising a flexible substrate, a transition layer, a buffer layer, a drive layer, a functional layer, and a thin-film encapsulation layer. The transition layer covers one side of the flexible substrate; the buffer layer covers one side, away from a rigid carrier, of the transition layer; the drive layer covers one side, away from the transition layer, of the buffer layer; the functional layer covers one side, away from the buffer layer, of the drive layer; and the thin-film encapsulation layer covers the surface of the functional layer. According to the invention, a sulfydryl-containing transition layer is modified on a flexible substrate by means of sulfydryl modification to realize tight adhesion between the flexible substrate and a buffer layer in a drive layer, so that the adhesion force between the flexible substrate and the buffer layer is greatly enhanced by means of chemical adsorption.
