1. A display apparatus comprising:
a plurality of sub-pixel regions at which color light is emitted to display an image, the plurality of sub-pixel regions including a first sub-pixel region, a second sub-pixel region, and a third sub-pixel region;
an organic light-emitting device substrate which generates and emits a light, the organic light-emitting device substrate comprising a cyan organic light-emitting device substrate which emits cyan light; and
in order from the organic light-emitting device substrate:
a first inorganic material layer;
an organic material layer comprising:
a first color control element which corresponds to the first sub-pixel region, includes a first quantum dot converting a color of the emitted light from the organic light-emitting device substrate to a first color and emits light of the first color;
a second color control element which corresponds to the second sub-pixel region, includes a second quantum dot converting the color of the emitted light from the organic light-emitting device substrate to a second color and emits light of the second color; and
a third color control element which corresponds to the third sub-pixel region, and includes a third quantum dot converting the color of the emitted light from the organic light-emitting device substrate to a third color, or a light-scattering element maintaining the color of the emitted light from the organic light-emitting device substrate;
a second inorganic material layer; and
a color filter layer comprising:
a first color filter corresponding to the first color control element,
a second color filter corresponding to the second color control element, and
a third color filter corresponding to the third color control element or the light-scattering element.
