1. A display substrate, comprising a base substrate and a plurality of pixel units on the base substrate, wherein each pixel unit comprises: a plurality of sub-pixels arranged in sequence in a first direction, each sub-pixel comprising a sub-pixel driving circuitry and a light-emitting element coupled to each other, and the sub-pixel driving circuitry being configured to provide a driving signal to the light-emitting element; and a light shielding layer, at least a part of the light shielding layer being arranged between the sub-pixel driving circuitry and the base substrate, wherein the display substrate further comprises a plurality of scanning lines, each scanning line comprises at least a part extending in the first direction and is coupled to a corresponding sub-pixel driving circuitry, and the scanning line is arranged at a same layer as the light shielding layer;
wherein the display substrate further comprises an auxiliary scanning line arranged at a side of a corresponding scanning line away from the base substrate and coupled to the corresponding scanning line and a sub-pixel driving circuitry in a corresponding sub-pixel; and
wherein the auxiliary scanning line comprises a first auxiliary scanning pattern, a second auxiliary scanning pattern and a third auxiliary scanning pattern, the third auxiliary scanning pattern is arranged between the first auxiliary scanning pattern and the second auxiliary scanning pattern, the first auxiliary scanning pattern and the second auxiliary scanning pattern are coupled to the sub-pixel driving circuitry in the corresponding sub-pixel, and the third auxiliary scanning pattern is coupled to the corresponding scanning line, the first auxiliary scanning pattern and the second auxiliary scanning pattern, wherein the scanning line coupled to the third auxiliary scanning pattern comprises a first boundary and a second boundary arranged in a second direction, the second direction crosses the first direction, an orthogonal projection of the first boundary onto the base substrate partially overlaps an orthogonal projection of the first auxiliary scanning pattern onto the base substrate, and an orthogonal projection of the second boundary onto the base substrate partially overlaps an orthogonal projection of the second auxiliary scanning pattern onto the base substrate.
