Abstract
According to one embodiment, a display device includes a liquid crystal display substrate and a color separation element substrate. The display substrate has a stripe structure in which different color filters are alternately arranged in a display area along a first direction and the same color filters are arranged along a second direction orthogonal to the first direction, and the different color filters are compartmentalized by frames along the first direction and the second direction. The element substrate has color separation grooves formed along the first direction in the display area, and grooves formed along the second direction in a region thereof where the color separation grooves are formed, so as to oppose the frame of the display substrate.
