Abstract: A display apparatus includes multiple light-emitting devices are disposed on a substrate, multiple color conversion layers disposed on the substrate and corresponding to the light-emitting devices, and multiple banks disposed between adjacent ones of the color conversion layers. Each of the banks includes first scattering particles, second scattering particles, and a polymer host. A refractive index (n1) of the first scattering particles is greater than a refractive index (n0) of the polymer host. The refractive index (n1) of the first scattering particles and a refractive index (n2) of the second scattering particles are different.
