The sub-pixels in each row includes first sub-pixels, second sub-pixels and third sub-pixels arranged alternately, and two adjacent rows of sub-pixels are arranged in a staggered manner. In every two adjacent rows of sub-pixels, each first sub-pixel in one row of sub-pixels and the second sub-pixel and the third sub-pixel adjacent to the first sub-pixel in another row of sub-pixels form a pixel. White brightness centers of the pixels in a same pixel row are located on a same straight line, and a brightness center of the first sub-pixel is not on a same straight line as the brightness centers of the second sub-pixel and the third sub-pixel located in a same sub-pixel row.
