Abstract
A display device includes: a first pixel, a second pixel, and a third pixel from which lights of different colors are respectively emitted; in the first pixel, a first light conversion layer overlapping a first color filter; in the second pixel, a second light conversion layer overlapping a second color filter; and in the third pixel, a third light conversion layer overlapping a third color filter. The first light conversion layer, the second light conversion layer, and the third light conversion layer respectively include a quantum dot, and an amount of the quantum dot included in the first light conversion layer is larger than each of amounts of the quantum dot respectively included in the second light conversion layer and the third light conversion layer.
