Abstract: A display apparatus including a first sub-pixel, a second sub-pixel, and a third sub-pixel respectively representing different colors is provided. The apparatus includes an upper substrate, a functional layer disposed over the upper substrate and including a first quantum-dot layer and a second quantum-dot layer, and a color filter layer between the upper substrate and the functional layer and including a first color filter, a second color filter, and a third color filter. The first color filter corresponds to the first sub-pixel, the second color filter corresponds to the second sub-pixel, and the third color filter corresponds to the third sub-pixel. The first sub-pixel is a green sub-pixel, and a full width at half maximum of a transmission spectrum of the first color filter is in a range of about 45 nm to about 49 nm.

Abstract: A display device includes a first pixel, a third pixel, and a third pixel emitting light of different colors, light-emitting diodes corresponding to the first pixel, the second pixel, and the third pixel and emitting light of a same color, and a function layer disposed in a direction in which the light-emitting diodes emit light and including a first color conversion layer corresponding to a first emission area of the first pixel, a second color conversion layer corresponding to a second emission area of the second pixel, and a transmitting layer corresponding to a third emission area of the third pixel. The first color conversion layer includes first quantum dots, the second color conversion layer includes second quantum dots, and each of the first color conversion layer, the second color conversion layer, and the transmitting layer include a base resin in which a plurality of pores are defined.
