1. A display device, comprising a display substrate, wherein the display substrate comprises a plurality of first subpixels, a plurality of second subpixels and a plurality of third subpixels, wherein
in a first direction, the first subpixels and the third subpixels are arranged alternately to form a plurality of first subpixel rows, the second subpixels are arranged to form a plurality of second subpixel rows, and the first subpixel rows and the second subpixel rows are arranged alternately in a second direction;
lines connecting centers of two first subpixels and two third subpixels in two adjacent rows and two adjacent columns form a first virtual quadrilateral, the two first subpixels are arranged at two opposite vertices of the first virtual quadrilateral respectively, the two third subpixels are arranged at the other two opposite vertices of the first virtual quadrilateral respectively, and a corresponding second subpixel is located within the first virtual quadrilateral; and
lines connecting centers of two second subpixels A and B, one first subpixel and one third subpixel in adjacent three rows and adjacent three columns form a virtual parallelogram, the two second subpixels A and B are arranged at two opposite vertices of the virtual parallelogram respectively, the first subpixel and the third subpixel are arranged at the other two opposite vertices of the virtual parallelogram respectively, a line connecting the centers of the second subpixel A and the third subpixel is located on a first straight line, a distance between an orthogonal projection of the center of the first subpixel onto the first straight line and the center of the second subpixel A is x, and the virtual parallelogram comprises an interior angle close to 90°;
wherein the display device further comprises a spacer adjacent to two second subpixels, one first subpixel and one third subpixel, wherein a minimum distance between boundaries of the first subpixel and the third subpixel adjacent to the spacer is greater than a minimum distance between boundaries of at least a part of first subpixels and third subpixels adjacent to each other.
