1. A display substrate, comprising:
a substrate;
a plurality of pixel units arranged on the substrate in an array in a row direction and a column direction, wherein the plurality of pixel units comprise at least a first pixel unit comprising a first light-emitting region and a first non-light-emitting region;
a first light-emitting element arranged in the first light-emitting region, wherein the first light-emitting element comprises a first electrode, a light-emitting layer and a second electrode;
a scan driving circuit arranged in the first non-light-emitting region; and
a first auxiliary electrode arranged on a side of the scan driving circuit away from the substrate, wherein the first auxiliary electrode is located in a first partial region in the first non-light-emitting region,
wherein the first auxiliary electrode is arranged in the row direction or the column direction; the scan driving circuit comprises a plurality of scan driving sub-circuits located in a second partial region in the first non-light-emitting region; an orthographic projection of the first partial region in the first non-light-emitting region on the substrate overlaps an orthographic projection of the second partial region in the first non-light-emitting region on the substrate, the first auxiliary electrode is electrically connected to the second electrode, and the first auxiliary electrode is located in the same layer as the first electrode.
