1. A light emitting substrate, comprising:
a base substrate, comprising a display region and a peripheral region located on at least one side of the display region;
at least one light emitting element, located in the display region;
at least one anti-static trace, located in the display region, the at least one anti-static trace being configured to surround the at least one light emitting element; and
a ground trace, located in the peripheral region, the ground trace being electrically connected with the at least one anti-static trace;
wherein adjacent anti-static traces in the display region constitute an integrated structure, or the adjacent anti-static traces in the display region are electrically connected through a first connection electrode; and
the anti-static trace comprises: a first extension portion and a first connection portion connected to each other, wherein an orthographic projection of the first extension portion on the base substrate is annular; the first connection portion of the anti-static trace and a first connection portion of another anti-static trace constitute an integrated structure, or the first connection portion of the anti-static trace is electrically connected with a first connection portion of another anti-static trace through the first connection electrode.
