Abstract
A display substrate includes a supporting material layer having at least one flexible material sub-layer and at least one blocking sub-layer, which can be alternately and successively arranged in layers. One blocking sub-layer is at a topmost sub-layer of the supporting material layer, and is provided with a well, located in a display area and configured for accommodating a display component therewithin. One or more of the at least one flexible material sub-layer or the at least one blocking sub-layer is configured as a target material layer. The target material layer includes a planar portion and a protruding portion over the planar portion. An orthographic projection of the protruding portion on a bottom surface of the supporting material layer forms a ring-like structure having an opening that covers an orthographic projection of a bottom surface of the well on the bottom surface of the supporting material layer.
