the four third sub-pixels are arranged along the column direction and a straight line along the column direction passes through all of the four third sub-pixels,

each of the plurality of first sub-pixels is a red sub-pixel, each of the plurality of second sub-pixels is a blue sub-pixel, and each of the plurality of third sub-pixels is a green sub-pixel,

the plurality of pixel groups are arranged in an array in a plane defined by the column direction and the row direction, the column direction is a direction in which a line connecting centers of any two third sub-pixels in each of the plurality of pixel groups extends, the row direction is a direction in which a line connecting centers of one first sub-pixel and one second sub-pixel in each of the plurality of pixel groups extends and is perpendicular to the column direction,

each of the first sub-pixel, the second sub-pixel and the third sub-pixel has a planar shape of polygon, the first sub-pixel has a side parallel to the column direction, the second sub-pixel has a side parallel to the column direction, and the third sub-pixel has a side parallel to the column direction.

2 . The display substrate according to claim 1 , wherein, in one sub-pixel group, a length of a side of the first sub-pixel farthest from the third sub-pixels in the row direction is smaller than a maximum size of the first sub-pixel in the column direction, and a length of a side of the second sub-pixel farthest from the third sub-pixel in the row direction is smaller than a maximum size of the second sub-pixel in the column direction.

3 . The display substrate according to claim 1 , wherein, the first sub-pixel in one sub-pixel group is adjacent to the second sub-pixel in an adjacent sub-pixel group, the second sub-pixel in one sub-pixel group is adjacent to the first sub-pixel in an adjacent sub-pixel group, and a distance between the first sub-pixel and the second sub-pixel in one sub-pixel group and in one row is different from a distance between the first sub-pixel in one sub-pixel group and the second sub-pixel in the adjacent sub-pixel group which are in the same row.

4 . The display substrate according to claim 1 , wherein, in one sub-pixel group, the first sub-pixel and the second sub-pixel located on the same side of the four third sub-pixels have mutually opposite and parallel sides, and the parallel sides are parallel to at least one side of the third sub-pixels.
