Abstract

Provided are a display substrate and a related device, belonging to the technical field of display. The display substrate includes a first sub-pixel and a second sub-pixel provided on a base substrate and having different colors. An orthographic projection of a first organic light-emitting layer of the first sub-pixel and an orthographic projection of a second organic light-emitting layer of the second sub-pixel onto the base substrate have an overlapping area, an insulating blocking layer is provided between the first organic light-emitting layer and the second organic light-emitting layer, and an orthographic projection of the blocking layer onto the base substrate covers at least part of the overlapping area. The technical solution of the present disclosure can prevent crosstalk between adjacent pixels.
