Abstract: A display device including a plurality of pixels disposed on a substrate, in which each pixel includes a first subpixel, a second subpixel adjacent to the first subpixel, and a third subpixel adjacent to the second subpixel, the second subpixel disposed between the first subpixel and the third subpixel; a first color filter disposed in the first subpixel, and configured to emit light having a first color; a second color filter disposed in the second subpixel, and configured to emit light having a second color; and a third color filter disposed in the third subpixel, and configured to emit light having a third color. Further, an upper surface of the second color filter is disposed a greater distance from the substrate than an upper surface of the first color filter, and the first subpixel further includes a first light path changing layer disposed on the first color filter and contacting a first side surface of the second color filter.
