Abstract
A display substrate and a display device are provided. Sub-pixels in the display substrate includes a light emitting element including a light emitting region. The light emitting element includes a light emitting functional layer, a first electrode and a second electrode. One defining structure is disposed between the light emitting regions of two adjacent sub-pixels having different colors. The adjacent sub-pixels include a first sub-pixel and a second sub-pixel. A ratio of a distance between edges, close to each other, of the light emitting region of the first sub-pixel and the one defining structure to a distance between edges, close to each other, of the light emitting region of the second sub-pixel and the one defining structure is 0.1 to 0.8. At least one layer of the light emitting functional layer is disconnected at an edge of the structure.
