    Abstract: A light-emitting diode chip configured to emit light of a first wavelength range and light of a second wavelength range, including a substrate, a light-emitting structure disposed on a first surface of the substrate, the light-emitting structure including an active layer disposed between a first conductivity-type semiconductor layer and a second conductivity-type semiconductor layer, and configured to emit light of the first wavelength range, and first and second distributed Bragg reflectors (DBRs) disposed on a second surface of the substrate. The first DBR is disposed closer to the substrate than the second DBR, the first wavelength range comprises a blue wavelength range, the first DBR comprises a higher reflectivity for light of the second wavelength range than for light of the first wavelength range, and the second DBR comprises a higher reflectivity for light of the first wavelength range than for light of the second wavelength range.

    Abstract: A light emitting device includes a short wavelength light emitting portion, a long wavelength light emitting portion, and a coupling layer combining the short wavelength emitting portion and the long wavelength light emitting portion. Each of the short wavelength light emitting portion and the long wavelength light emitting portion includes a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer. The active layer of the long wavelength light emitting portion contains more Indium (In) than the active layer of the short wavelength light emitting portion, and the short wavelength light emitting portion emits light of a shorter wavelength than that of light emitted from the long wavelength light emitting portion.
