Abstract
A light emitting device includes a substrate, a light emitting unit, and a first optical structure. The light emitting unit is disposed on a top surface of the substrate. The first optical structure is disposed on the light emitting unit. The first optical structure includes a plurality of first nanostructures and a plurality of first quantum dot units. Each of the first quantum dot units is disposed in the first nanostructure. The light emitting unit is used to generate a first color light. Each of the first quantum dot units is used to be excited by the first color light to generate a second color light different from the first color light.
