Abstract: A display device has first and second pixel columns and at least one third pixel column. The first pixel column includes first pixels to emit light of a first color and a second pixels to emit light of a second color alternately arranged in a first direction. The second pixel column includes the first pixels and the second pixels arranged in the first direction in a reverse order from the first pixel column. The at least one third pixel column includes third pixels to emit light of a third color and arranged in the first direction. The first and second pixel columns are alternately arranged in a second direction crossing the first direction. The third pixel column is between the first and second pixel columns. The second pixel of the first pixel column and the second pixel of the second pixel column are connected to a same data line.
