Abstract

A display substrate includes a flexible substrate, a cathode layer located on a first side of the flexible substrate and at least one insulating layer located between the flexible substrate and the cathode layer. The flexible substrate includes at least one stretchable region, the stretchable region extends from the display area to the non-display area, and the stretchable region is provided with a plurality of holes arranged in an array therein. A border of the cathode layer is located in the non-display area. The at least one insulating layer is configured to expose the plurality of holes, the at least one insulating layer is provided with at least one partition groove therein, an orthographic projection of a partition groove on the flexible substrate is disposed around a hole of the plurality of holes, and the partition groove is configured to partition the cathode layer.
