A pixel arrangement structure includes a plurality of sub-pixel repetition units arranged end to end along a first direction and disposed in parallel along a second direction each forming two pixel units and each comprising two first color sub-pixels, two second color sub-pixels and one third color sub-pixel. A line connecting centers of the first color sub-pixels and a line connecting centers of the second color sub-pixels are both parallel to the first direction. Each of the first and the second color sub-pixels independently belong to one of the two pixel units respectively, the third color sub-pixel is shared by the two pixel units. Areas of one first color sub-pixel, one second color sub-pixels and one third color sub-pixel are different. In two adjacent sub-pixel repetition units in the first direction, at least two adjacent sub-pixels are of same color and are respectively disposed in the two sub-pixel repetition units.
