Abstract

A display substrate has at least one display region and at least one non-display region, and a non-display region is located at at least one side of a display region. The display substrate includes a base, a plurality of light-emitting devices, and an encapsulation layer. The plurality of light-emitting devices are located in the at least one display region and disposed on a side of the base. The encapsulation layer is disposed on a side of the plurality of light-emitting devices facing away from the base, and configured to encapsulate the plurality of light-emitting devices. A surface, proximate to the base, of a portion of the encapsulation layer located in the non-display region is unevenly arranged.
