Abstract
A display apparatus includes an organic light-emitting device (“OLED”) substrate which generates and emits a first light, and an encapsulation layer to which the emitted first light from the OLED substrate is incident and from which a second light is emitted. The encapsulation layer includes an inorganic material layer and an organic material layer alternately stacked with each other. The organic material layer includes a plurality of color control elements which color-convert the emitted first light incident to the encapsulation layer. The plurality of color control elements may include a first and second color control element including a first and second quantum dot with which a color of the emitted first light incident to the encapsulation layer is converted to a first and second color, respectively.
