Abstract: A display device includes a base substrate and first to third color filter layers. The base substrate includes pixel regions and a light blocking region. A pixel region from among the pixel regions includes first to third light emitting regions emitting light of different colors from each other. The light blocking region surrounds the first to third light emitting regions. The first color filter layer is on the base substrate, has a first color, and overlaps the first light emitting regions and an entirety of the light blocking region. The second color filter layer is on the base substrate, has a second color, and overlaps the second light emitting regions and a portion of the light blocking region. The third color filter layer is on the base substrate, has a third color, and overlaps the third light emitting regions and an entirety of the light blocking region.
