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.
