Display substrate, fine metal mask set and display device

A display substrate comprising:

• a plurality of first pixels and a plurality of second pixels alternately arranged in both a first direction and a second direction,
• wherein each of the first pixels comprises a first sub-pixel and a second sub-pixel, and each of the second pixels comprises a third sub-pixel and another second sub-pixel,
• wherein the second sub-pixels are evenly arranged in a matrix,
• wherein the first sub-pixel and the third sub-pixel are both in a polygonal shape, and are alternately arranged in both the first direction and the second direction,
• wherein in a group consisting of one first sub-pixel and one third sub-pixel adjacent to each other in the first direction, a line connecting a vertex of the one first sub-pixel closest to the one third sub-pixel with a vertex of the one third sub-pixel closest to the one first sub-pixel intersects an extension line in the first direction and an extension line in the second direction,
• wherein the first sub-pixel, the second sub-pixel, and the third sub-pixel are in a shape selected from at least one of square or rhombus, first diagonal lines of the first sub-pixel, the second sub-pixel, and the third pixel are parallel to each other, and second diagonal lines of the first sub-pixel, the second sub-pixel, and the third sub-pixel are parallel to each other, and
• wherein an included angle between each of the first diagonal lines and the first direction is substantially greater than 0° and less than 45°, and an included angle between each of the second diagonal lines and the second direction is substantially greater than 0° and less than 45°.
