Display substrate, display device and high-precision metal mask

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 arranged alternately 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 arranged alternately, and the first direction is approximately perpendicular to the second direction;
• 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 that is non-square, and a second sub-pixel is within the virtual quadrilateral;
• wherein four virtual quadrilaterals form a hexagon comprising two parallel edges, wherein:
• the four virtual quadrilaterals share one first sub-pixel, a first edge of the two parallel edges passes through a first sub-pixel, a third sub-pixel and another first sub-pixel, a second edge of the two parallel edges passes through a first sub-pixel, a third sub-pixel and another first sub-pixel, and a connection line of centers of two third sub-pixels on the two parallel edges does not pass through a center of the first sub-pixel shared by the four virtual quadrilaterals;
• or,
• the four virtual quadrilaterals share one third sub-pixel, a first edge of the two parallel edges passes through a third sub-pixel, a first sub-pixel and another third sub-pixel, a second edge of the two parallel edges passes through a third sub-pixel, a first sub-pixel and another third sub-pixel, and a connection line of centers of two first sub-pixels on the two parallel edges does not pass through a center of the third sub-pixel shared by the four virtual quadrilaterals.
