Abstract: An aspect of the present disclosure relates to an electronic device, and more particularly, to an electronic device that may include: a substrate; a plurality of light emitting devices, disposed on the substrate; a wavelength converting layer, disposed on the substrate, wherein the plurality of the light emitting devices emit a light of same color, wherein light emitted from the light emitting devices is converted by going through the wavelength converting layer, wherein the converted light is extracted to outside of the electronic device, and has a wavelength longer than that of the light emitted from the light emitting devices. Through this, an electronic device can be provided emitting light having a wavelength from which effects of inflammation treatments and skin regeneration can be acquired.

Abstract: Discussed are a light emitting device and a lighting apparatus, which include a substrate, a light emitting diode on the substrate, a refractive index adjustment layer on the light emitting diode, a light scattering layer on the refractive index adjustment layer, a first electrode disposed on the light scattering layer and connected to the light emitting diode, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer. The light scattering layer has a smaller refractive index than the refractive index adjustment layer.
