1. A display substrate, comprising: first sub-pixels, second sub-pixels and third sub-pixels;
wherein in a first direction, the first sub-pixels and the third sub-pixels are alternately arranged to form first sub-pixel rows, and the second sub-pixels form second sub-pixel rows;
wherein in a second direction, the first sub-pixel rows and the second sub-pixel rows are alternately arranged, and the first direction and the second direction are substantially perpendicular;
wherein two first sub-pixels and two third sub-pixels in two adjacent rows and two adjacent columns form a 2*2 array; in the 2*2 array, the two first sub-pixels are in different rows and in different columns, the two third sub-pixels are in different rows and in different columns, connection lines of centers of the two first sub-pixels and the two third sub-pixels form a virtual quadrilateral, and a second sub-pixel is within the virtual quadrilateral;
wherein: a third sub-pixel has a symmetry axis along a first oblique line direction and a symmetry axis along a second oblique line direction, and a width of the third sub-pixel in the first oblique line direction is different from that in the second oblique line direction; and/or, a first sub-pixel has a symmetry axis along the first oblique line direction and a symmetry axis along the second oblique line direction, and a width of the first sub-pixel in the first oblique line direction is different from that in the second oblique line direction;
wherein the second oblique line direction is substantially perpendicular to the first oblique line direction, and the second oblique line direction and the first oblique line direction intersect both the first direction and the second direction;
wherein in at least one virtual quadrilateral, a distance from the second sub-pixel to a first one of the third sub-pixels is L1, a distance from the second sub-pixel to a second one of the third sub-pixels is L2, and distances from the second sub-pixel to the two first sub-pixels are both L1, where L2 is greater than L1; or,
in at least one virtual quadrilateral, each of distances from the second sub-pixel to the two third sub-pixels and distances from the second sub-pixel to the two first sub-pixels is L1; or,
in at least one virtual quadrilateral, distances from the second sub-pixel to the two third sub-pixels are both L1, a distance from the second sub-pixel to a first one of the first sub-pixels is L1, and a distance from the second sub-pixel to a second one of first sub-pixels is L2, where L2 is greater than L1;
or,
wherein the virtual quadrilateral is a right-angled trapezoid, two interior angles of the virtual quadrilateral each are 90°, one of other two interior angles of the virtual quadrilateral is an obtuse angle, and one of the other two interior angles of the virtual quadrilateral is an acute angle.
