Abstract: A display device according to an embodiment includes a substrate including a plurality of gate lines and a plurality of data lines crossing the plurality of gate lines, and a sub-pixel array structure including a sub-pixel group corresponding to the substrate. The sub-pixel group includes a first sub-pixel, a second sub-pixel in a column different from the first sub-pixel, and third sub-pixels divided in two rows and in two columns with at least one of the first sub-pixel and the second sub-pixel therebetween, wherein the first sub-pixel is in a first column, the second sub-pixel is in a third column, and the third sub-pixels are in second and fourth columns, and wherein a ratio between numbers of the first, second and third sub-pixels is 1:1:4.
