1. A display substrate, comprising: a display area and a non-display area located at a periphery of the display area, wherein the display area includes a plurality of pixel opening areas and a pixel spacing area located between the pixel opening areas; the display substrate further includes:
a first electrode, wherein at least part of the first electrode is located in the pixel spacing area, an orthographic projection of the first electrode on a substrate of the display substrate does not overlap an orthographic projection of the pixel opening area on the substrate;
a second electrode electrically connected to the first electrode and located in the non-display area; and
an auxiliary cathode layer, a first insulating layer, an anode layer, a second insulating layer, and a cathode layer that are sequentially stacked on the substrate in a direction away from the substrate, wherein the auxiliary cathode layer is electrically connected to the cathode layer through a connection via hole, and the auxiliary cathode layer includes a metal layer.
