Abstract: A display substrate has a display area, an opening area and an isolation area located between the display area and the opening area and surrounding the opening area, and the display area is disposed at least partially around the opening area. The display substrate includes a flexible base having a via hole located in the opening area. The flexible base includes an amorphous silicon layer. The amorphous silicon layer includes a first portion located in the isolation area and a second portion located in the display area, and a thickness of the first portion is greater than a thickness of the second portion.

Abstract: The present disclosure provides a display substrate, a display device, and a manufacturing method of a display substrate. The display substrate of the present disclosure includes a substrate, a pixel defining layer located on the substrate, and a plurality of organic light emitting diodes arranged in an array, with a plurality of pixel accommodating holes provided in the pixel defining layer, and the organic light emitting diodes in one-to-one correspondence with the pixel accommodating holes, and located in the corresponding pixel accommodating holes; and a plurality of supporting structures in one-to-one correspondence with the pixel accommodating holes are formed on a side of the pixel defining layer distal to the substrate, and orthographic projections of the supporting structures on the pixel defining layer surround the corresponding pixel accommodating holes.
