1. A display device comprising:
a substrate;
a multi-layer stack disposed on the substrate, wherein the multi-layer stack comprises a quantum dot (QD) film configured to:
emit a first light having a first peak wavelength through a first portion of the substrate, and
emit a second light having a second peak wavelength through a second portion of the substrate; and
a microLED or a miniLED disposed on the substrate and configured to emit a third light having a third peak wavelength through a third portion of the substrate, wherein the first, second, third peak wavelengths are different from each other.
