1. A display apparatus comprising:
a substrate;
a first light-emitting device, a second light-emitting device, and a third light-emitting device, each comprising a first-color emission layer and being over the substrate;
a second-color quantum dot layer over the second light-emitting device;
a third-color quantum dot layer over the third light-emitting device;
a low refractive index layer over the second-color quantum dot layer and the third-color quantum dot layer to correspond to the first through third light-emitting devices, and comprising a matrix part and a plurality of particles in the matrix part, wherein the matrix part comprises a first portion away from the first through third light-emitting devices and comprising fluorine, and a second portion between the first through third light-emitting devices and the first portion of the matrix part, and wherein the first and second portions of the matrix part form an integral body;
a first-color color filter layer over the low refractive index layer to correspond to the first light-emitting device;
a second-color color filter layer over the low refractive index layer to correspond to the second light-emitting device; and
a third-color color filter layer over the low refractive index layer to correspond to the third light-emitting device.
