Abstract

A display device includes an organic emission layer in which a first pixel area, a second pixel area and a third pixel area are defined, a color filter layer disposed on the organic emission layer and including first to third color filters overlapping the first to third pixel areas, respectively, where the first to third color filters emit first light to third light, respectively, a first optical filter layer disposed on the color filter layer and which transmits at least one of the first light and the second light and reflects or absorbs the third light, and a light-focusing layer disposed between the color filter layer and the organic emission layer and including first to third light-focusing parts overlapping the first to third pixel areas, respectively, where at least one of the first to third color filters includes quantum dots.
