Abstract
The display substrate includes: a substrate, 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; the anode layer includes a plurality of anode patterns spaced apart from each other, and an anode spacing area is formed between adjacent anode patterns; an orthographic projection of the auxiliary cathode layer on the substrate and an orthographic projection of the cathode layer on the substrate have an auxiliary overlapping area, and the auxiliary cathode layer is electrically connected to the cathode layer through a connection via hole in the auxiliary overlapping area; an orthographic projection of the connection via hole on the substrate is located inside the orthographic projection of the anode spacing area on the substrate.
