1. A display apparatus comprising:
a first sub-pixel, a second sub-pixel, and a third sub-pixel, which emit light of different colors from one another;
light-emitting diodes corresponding to the first sub-pixel, the second sub-pixel, and the third sub-pixel, respectively, and which emit light of a same color;
a functional layer arranged in a light-emitting direction of the light-emitting diodes and comprising a first quantum dot layer corresponding to an emission area of the first sub-pixel and a second quantum dot layer corresponding to an emission area of the second sub-pixel; and
a light absorption layer disposed between the light-emitting diodes and the functional layer,
wherein at least a portion of the light absorption layer is disposed between the light-emitting diode corresponding to the first sub-pixel and the first quantum dot layer,
wherein the first sub-pixel is a red sub-pixel, and
wherein the light absorption layer comprises a pigment or a dye, which absorbs red light.
