Abstract: A display substrate and a display device are provided. The display substrate includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. Each sub-pixel includes a light-emitting region. Sides of each light-emitting region or extension lines of the sides are sequentially connected to form a polygon. Vertexes of the polygon of at least a part of the sub-pixels have non-overlapped regions with angle portions of the corresponding light-emitting regions. Corners of the light-emitting region of at least one sub-pixel at least include a first angle portion. An area of a non-overlapped region between the first angle portion and a vertex angle of the polygon corresponding to the first angle portion is greater than an area of a non-overlapped region between each angle portion among at least part of remaining angle portions and a vertex angle of the polygon corresponding to the each angle portion.

Abstract: A display substrate and a display device. The display substrate includes a first sub-pixel (111), a second sub-pixel (112), and a first spacer (0101). A line connecting the center (C1) of the first sub-pixel (111) and the center (C2) of the second sub-pixel (112) is a center line (CL1); the center line (CL1) is not perpendicular to a first direction (X); the first direction (X) is at least one of the row direction or the column direction. The first spacer (0101) is disposed between the first sub-pixel (111) and the second sub-pixel (112), and the extension direction (E01) of first spacer (0101) between the first sub-pixel (111) and the second sub-pixel (112) is not perpendicular to the first direction (X). Therefore, the display substrate can improve the different viewing angle color cast and improve the display quality.
