Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. A pixel region is provided with a light emission function layer on a base substrate of the display substrate, and a separation region is provided with at least one first barrier structure. The first barrier structure includes a stopper pattern and a first separation component. A side surface of the first separation component has a recess, and a portion of the light emission function layer extending to the separation region is disconnected on the side of the first separation component. The separation region is provided with an inorganic layer structure on the base substrate. The inorganic layer structure includes 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 away from the base substrate.
