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.

Abstract: A display apparatus includes: a first substrate on which a plurality of light-emitting devices are arranged; a plurality of light controllers arranged above the first substrate and corresponding to the plurality of light-emitting devices; and a plurality of banks between the plurality of light controllers, wherein each bank of the plurality of banks includes a black pigment and a scattering agent. Because the display apparatus according to an embodiment includes a bank including a black pigment and a scattering agent, color mixing between pixels is prevented or reduced, and light efficiency is increased.
