1. A display substrate, comprising:
a substrate;
a compensation electrode arranged on one side of the substrate;
an auxiliary electrode arranged on one side of the compensation electrode away from the substrate and coupled to the compensation electrode, a first notch being formed in a side surface of the auxiliary electrode, and at least a part of the first notch extending in a direction parallel to the substrate;
a light-emitting functional layer arranged at one side of the auxiliary electrode away from the substrate and interrupted at the first notch; and
a cathode layer arranged on one side of the light-emitting functional layer away from the substrate and coupled to the auxiliary electrode at the first notch,
wherein the auxiliary electrode comprises a first electrode layer, a second electrode layer, and a third electrode layer laminated one on another in a direction away from the substrate, the first electrode layer is coupled to the compensation electrode, the light-emitting functional layer comprises a first portion and a second portion separated from each other at the first notch, the first portion is arranged at one side of the third electrode layer away from the substrate, the second portion is arranged at one side of the first electrode layer away from the substrate, a spacer region is formed between the second portion and the second electrode layer arranged at the first notch, and the cathode layer is coupled to the first electrode layer at the spacer region.
