摘要： A display substrate and a display device. The display substrate comprises a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. Each sub-pixel comprises a light-emitting region. Respective sides of each light-emitting region or extension lines thereof are sequentially connected to form a polygon. Multiple vertexes of the polygons of at least a portion of the sub-pixels have regions not overlapping with multiple corners of the corresponding light-emitting regions. Multiple corners of the light-emitting region of at least one sub-pixel at least include a first corner. An area of a region of the first corner not overlapping with a corresponding vertex of the polygon is larger than areas of regions of at least a portion of the remaining corners not overlapping with corresponding vertexes of the polygon. In an embodiment of the present disclosure, arrangement of a first corner on at least one sub-pixel facilitates adjusting centers of brightness in at least a portion of a display region, thereby realizing uniform distribution of the centers of brightness.
