Abstract

A semiconductor device includes a circuit substrate, a light-emitting layer, a structure, and a light-emitting diode chip. The light-emitting layer is located on the circuit substrate and emits a first color light with a first wavelength range. The structure is disposed between the light-emitting layer and the circuit substrate. The structure emits a second color light with a second wavelength range. The light-emitting diode chip is located on the circuit substrate without overlapping the structure in a vertical direction. The light-emitting diode chip emits a third color light with a third wavelength range. The first wavelength range is between the second wavelength range and the third wavelength range.
