Abstract

A display device with a plurality of sub-pixel groups is disclosed. Each of the sub-pixel groups comprises a first sub-pixel, located at a first column; a second sub-pixel, located at a second column adjacent to the first column; a third sub-pixel, located at a third column adjacent to the second column; a fourth sub-pixel, located at a fourth column adjacent to the third column; and a fifth sub-pixel, located at the fourth column; wherein the row of the second sub-pixel overlaps the row of the first sub-pixel; wherein the row of the third sub-pixel overlaps the row of the first sub-pixel; wherein the row of at least one of the fourth sub-pixel and the fifth sub-pixel overlaps the row of the first sub-pixel; wherein a sum of the heights of the fourth sub-pixel and the fifth sub-pixel is smaller than or equal to the height of the first sub-pixel.
