Abstract

A display apparatus includes an organic light-emitting device (OLED) substrate, a color control layer; a first optical layer to which the generated light of the organic light-emitting substrate is incident and from which wavelength range light is provided to the color control layer; and a second optical layer to which the wavelength-converted light of the color control layer is incident and from which display light is provided for displaying an image The first optical layer partially transmits and partially reflects light of a first wavelength range, and reflects light of a second wavelength range and light of a third wavelength range each different from the first wavelength range. The second optical layer reflects light of the first wavelength range, and transmits each of light of the second wavelength range and light of the third wavelength range.
