Abstract
A display substrate, a manufacturing method and a display device are disclosed. The display substrate includes a base substrate, and a light-shielding layer and a plurality of light-emitting units arranged at a display region of the base substrate. A plurality of imaging pin-holes is formed in the light-shielding layer, an orthogonal projection of each imaging pin-hole onto the base substrate does not overlap an orthogonal projection an active light-emitting region of the corresponding light-emitting unit onto the base substrate, and at least a part of a surface of the light-shielding layer adjacent to the light-emitting units is uneven.
