1. A display apparatus comprising:
a first pixel, a second pixel, and a third pixel which emit light of different colors;
a first quantum conversion layer arranged corresponding to an emission area of the first pixel and comprising a plurality of first quantum dots and a plurality of first metal nanoparticles; and
a second quantum conversion layer arranged corresponding to an emission area of the second pixel and comprising a plurality of second quantum dots and a plurality of second metal nanoparticles,
wherein the plurality of first quantum dots has an average size different from an average size of the plurality of second quantum dots, and
the plurality of first metal nanoparticles has an average size identical to an average size of the plurality of second metal nanoparticles, and outer shapes of the plurality of first metal nanoparticles and the plurality of second metal nanoparticles have sharper corners than virtual outer spherical shapes.
