    Abstract: A display device includes a first pixel and a second pixel, which are disposed adjacent to each other in a first direction and are alternately and repeatedly arranged. The first pixel includes a first sub-pixel, a second sub-pixel, and two third sub-pixels, which are arranged in a 2×2 matrix form. The second pixel includes a fourth sub-pixel, a fifth sub-pixel, and two sixth sub-pixels, which are arranged in a 2×2 matrix form. The first to third sub-pixels include sub-pixels having colors different from each other. The fourth to sixth sub-pixels include sub-pixels having colors different from each other. The first sub-pixel and the fourth sub-pixel include sub-pixels having the same color. The second sub-pixel and the fifth sub-pixel include sub-pixels having the same color. The third sub-pixels and the sixth sub-pixels include sub-pixels having the same color. The first pixel and the second pixel have a line symmetry relationship.

    Abstract: Provided is a display device. The display device includes a substrate and a first pixel and a second pixel, which are disposed adjacent to each other in a first direction parallel to a top surface of the substrate. Each of the first pixel and the second pixel is provided in plurality and is alternately and repeatedly arranged in the first direction. The first pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, which are sequentially arranged in the first direction. The second pixel includes a fourth sub-pixel, a fifth sub-pixel, and a sixth sub-pixel, which are sequentially arranged in the first direction. The first to third sub-pixels include sub-pixels having colors different from each other. The fourth to sixth sub-pixels include sub-pixels having colors different from each other. The third sub-pixel and the fourth sub-pixel include sub-pixels that are disposed adjacent to each other and have the same color. Each of the second sub-pixel and the fourth sub-pixel includes a blue sub-pixel.
