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.

Abstract: A display device includes: a first substrate including a display area; a thin film transistor positioned on the first substrate; a pixel electrode connected to the thin film transistor; a color filter overlapping the pixel electrode; a second substrate overlapping the first substrate; a liquid crystal layer positioned between the first substrate and the second substrate; and a stain correction layer positioned between the second substrate and the liquid crystal layer and including a semiconductor nanocrystal. The display area includes a first region and a second region excluding the first region. The stain correction layer is positioned in the first region.
