Pixel array and display device

A pixel array, comprising first sub-pixels, second sub-pixels and third sub-pixels;

• wherein
• the first sub-pixels and the third sub-pixels are alternately arranged along a first direction to form first pixel groups, and are alternately arranged along a second direction to form third pixel groups;
• the second sub-pixels are arranged along the first direction to form second pixel groups, and are arranged along the second direction to form fourth pixel groups;
• the first pixel groups and the second pixel groups are alternately arranged in the second direction;
• the third pixel groups and the fourth pixel groups are alternately arranged along the first direction;
• and
• a shape of each of the second sub-pixels comprises a polygon, a plurality of sides of the polygon comprise straight lines or arcs, and the shape of the second sub-pixel comprises at most one symmetry axis;
• and
• the shape of each of the second sub-pixels comprises a quadrangle, which comprises two pairs of opposite corners;
• in one pair of opposite corners, a closest distance from an intersection point between extension lines of two sides of one corner to a boundary of the second sub-pixel is different from a closest distance from an intersection point between extension lines of two sides of the other corner to the boundary of the second sub-pixel, and in the other pair of opposite corners, a closest distance from an intersection point between extension lines of two sides of one corner to the boundary of the second sub-pixel is equal to a closest distance from an intersection point between extension lines of two sides of the other corner to the boundary of the second sub-pixel or in the one pair of opposite corners, a distance from the intersection point between the extension lines of the two sides of one corner to a center of the second sub-pixel is equal to a distance from the intersection point between the extension lines of two sides of the other corner to the center of the second sub-pixel;
• at least one of the two pairs of opposite corners has a flat chamfer or a round chamfer.
