Abstract
A display apparatus includes a substrate; a plurality of light-emitting diodes (LED) disposed on the substrate, and a capping layer on each LED. Each LED emits one of a first light having a first wavelength, a second light having a second wavelength, and a third light having a third wavelength, where the first wavelength is less than the second wavelength, and the second wavelength is less than the third wavelength. Each capping layer has a different haze value for each of the first, second and third lights, or a different lens shape for each of the first, second and third lights.
