Claim 0:
1. A display substrate comprising:
a base substrate comprising a display area and a non-display area located at a periphery of the display area, wherein the non-display area comprises a fan-out area;
a signal line layer arranged on the base substrate and comprising a plurality of signal lines located in the fan-out area;
a first metal layer arranged on one side of the signal line layer away from the base substrate and comprising a first power line located in the non-display area;
a first electrode layer located on one side of the first metal layer away from the base substrate and comprising a first electrode portion, wherein an orthographic projection of the first electrode portion on the base substrate at least partially overlaps with an orthographic projection of the first power line on the base substrate, and the first electrode portion is electrically connected to the first power line; and
an organic insulating layer located between the first metal layer and the first electrode layer and having at least one groove located in the non-display area, wherein an orthographic projection of the organic insulating layer at an edge of the at least one groove on the base substrate at least partially overlaps, in a first area, with an orthographic projection of the fan-out area on the base substrate, and at least part of the first area does not overlap with the orthographic projection of the first electrode portion on the base substrate.
