Abstract: A display device according to an embodiment includes a circuit layer, a light-emitting element layer, an inorganic encapsulation film, a sub light control layer, a light control layer, a capping layer, and a color filter layer which are sequentially stacked each other. The sub light control layer includes a first to third sub light control parts, and a light control layer includes a bank and a first to third light control parts spaced apart from each other with the bank therebetween. Each of the sub light control layer and the light control layer includes quantum dots. The display device according to an embodiment includes the sub light control layer adj acent to the light-emitting element layer to exhibit improved light efficiency and color gamut.
