Claim 17:
18. A method for manufacturing a display substrate, the display substrate having a display region, the display region comprising a pixel region, a hole region and a separation region located between the pixel region and the hole region and surrounding the hole region, wherein the method comprises:
manufacturing a driver circuit layer on a base substrate in the pixel region, wherein the driver circuit layer comprises a conductive layer;
manufacturing an inorganic layer structure and at least one first barrier structure on the base substrate in the separation region; 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, 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;
forming a light emission function layer in the pixel region and the separation region on the base substrate formed with the driver circuit layer, the inorganic layer structure and the at least one first barrier structure, wherein a portion of the light emission function layer in the separation region is disconnected on the side of the first separation component.
