Claim 0:
1. A display substrate, comprising a display region, wherein the display region comprises a pixel region, a hole region and a separation region located between the pixel region and the hole region and surrounding the hole region;
the pixel region comprises a light emission function layer on a base substrate of the display substrate, and a driver circuit layer between the base substrate and the light emission function layer, wherein the driver circuit layer comprises a conductive layer;
the separation region is provided with at least one first barrier structure on the base substrate, wherein the first barrier structure comprises: a stopper pattern and a first separation component sequentially stacked in a direction away from the base substrate, the stopper pattern and the conductive layer are made on the same layer, a side surface of the first separation component has a recess, and a portion of the light emission function layer that extends to the separation region is disconnected on the side of the first separation component;
the separation region is further provided with an inorganic layer structure on the base substrate, wherein the inorganic layer structure comprises multiple stacked inorganic film layers, the stopper pattern is located between two adjacent inorganic film layers, and the first separation component is located on a side of the inorganic layer structure facing away from the base substrate.
