A pixel arrangement structure, comprising first sub-pixels, second sub-pixels, third sub-pixels, and fourth sub-pixels;

• centers of two of the first sub-pixels arranged opposite to each other and centers of two of the second sub-pixels arranged opposite to each other being taken as vertices and connected to form a virtual quadrilateral, the virtual quadrilateral comprising two equal sides arranged opposite to each other, a short side and a long side of the virtual quadrilateral arranged opposite to each other and connected to vertices of the equal sides;
• the short side of the virtual quadrilateral being not parallel to the long side of the virtual quadrilateral;
• one of the third sub-pixels or one of the fourth sub-pixels being arranged in the virtual quadrilateral, and the third sub-pixel and the fourth sub-pixel emitting light in a same color;
• and
• in a row direction, a connecting line of centers of the first sub-pixels in each row is a straight line;
• a connecting line of centers of the second sub-pixels in each row is a straight line;
• and a connecting line of centers of the third sub-pixels or the fourth sub-pixels in each row is a non-straight line.
