Display substrate and method for manufacturing the same, display device

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, the driver circuit layer comprises a transistor structure and a capacitor structure, the transistor structure comprises an active layer, a gate electrode and a source-drain electrode layer sequentially stacked in the direction away from the base substrate, the source-drain electrode layer comprises a source electrode and a drain electrode arranged in a same layer and made of a same material, the capacitor structure comprises a first electrode plate and a second electrode plate arranged oppositely in a direction perpendicular to the base substrate, the first electrode plate and the gate electrode are arranged in a same layer and made of a same material, the second electrode plate is located between the first electrode plate and the source-drain electrode layer;
• manufacturing 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, a side surface of the first separation component has a recess;
• forming a light emission function layer in the pixel region and the separation region on the base substrate formed with the driver circuit layer, an 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;
• wherein at least a part of the stopper pattern is arranged in a same layer as the gate electrode.
