1. A display substrate having a display area and a non-display area adjacent to the display area; the display substrate comprising:
a flexible substrate, the flexible substrate including at least one stretchable region, the stretchable region extending from the display area to the non-display area, and the stretchable region being provided with a plurality of holes arranged in an array therein;
a cathode layer located on a first side of the flexible substrate, the cathode layer extending from the display area to the non-display area, and a border of the cathode layer being located in the non-display area; and
at least one insulating layer located between the flexible substrate and the cathode layer, the at least one insulating layer being configured to expose the plurality of holes; wherein 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.
