Abstract:
A quantum dot light emitting device includes a grating device which includes a grating region that has a particular grating interval, and a quantum dot layer located above the grating region. The device provides high-purity color light based on a selection of a wavelength band by the grating region in correspondence with a wavelength band of light emitted from the quantum dot layer.
