Display substrate and display device

A display substrate, comprising:

• a plurality of sub-pixels, comprising a plurality of first color sub-pixels, a plurality of second color sub-pixels and a plurality of third color sub-pixels;
• wherein the plurality of first color sub-pixels and the plurality of third color sub-pixels are alternately arranged along a row direction and a column direction to form a plurality of first pixel rows and a plurality of first pixel columns, the plurality of second color sub-pixels are arrayed along the row direction and the column direction to form a plurality of second pixel rows and a plurality of second pixel columns, the plurality of first pixel rows and the plurality of second pixel rows are alternately arranged along the column direction and are shifted from each other in the row direction, and the plurality of first pixel columns and the plurality of second pixel columns are alternately arranged along the row direction and are shifted from each other in the column direction;
• wherein the plurality of sub-pixels comprise a plurality of light emitting regions, sides of each light emitting region or extension lines of the sides of each light emitting region are sequentially connected to form a polygon, and a plurality of vertex angles in the polygon of at least part of the plurality of sub-pixels have non-overlapped regions with a plurality of angle portions of a corresponding light emitting region;
• the plurality of angle portions of the light emitting region of at least one sub-pixel at least comprise 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 a first area, 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 is a second area, the first area is greater than the second area;
• the light emitting region of at least one sub-pixel with the first angle portion is an axisymmetric pattern, and at least one axis of symmetry in the axisymmetric pattern coincides with a bisector of the first angle portion, the bisector is parallel to one of the row direction and the column direction;
• in a same sub-pixel, a connecting line between vertices of two angle portions adjacent to the first angle portion divides the same sub-pixel into two parts, and the two parts have different areas.
