Display substrate, display device and high-precision metal mask

A display device, comprising a display substrate, wherein the display substrate comprises:

• 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 the second sub-pixel is within the virtual quadrilateral;
• wherein, for a plurality of distances from the centers of the two first sub-pixels and the centers of the two third sub-pixels corresponding to a same virtual quadrilateral to a center of the second sub-pixel, at least two distances among the plurality of distances are different;
• wherein:
• the 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, the first 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 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;
• in at least one virtual quadrilateral, the distances from the center of the second sub-pixel to the centers of the two third sub-pixels are not equal, and the distances from the center of the second sub-pixel to the centers of the two first sub-pixels are approximately equal;
• or,
• in at least one virtual quadrilateral, the distances from the center of the second sub-pixel to the centers of the two third sub-pixels are approximately equal, and the distances from the center of the second sub-pixel to the centers of the two first sub-pixels are not equal.
