Abstract: A display device includes a first substrate, pixel structures, and first, second, and third optical filters. The first substrate has a plurality of pixel regions each including first, second, and third sub-pixel regions. The pixel structures are disposed on the first substrate. The first, second, and third optical filters are disposed to overlap the first, second, and third sub-pixel regions, respectively, on the pixel structures. Each of the first, second, and third optical filters has a tetragon shape. A long axis of the tetragon is parallel to row or column directions of the pixel regions. The third optical filter overlaps a first virtual line located between a side of the first optical filter and a side of the second optical filter which is adjacent to the side of the first optical filter. The first virtual line extends parallel to the sides of the first and second optical filters.
