Abstract:
1. An organic electroluminescent device comprising: a transparent electrode transmissive with respect to visible light; a metal electrode reflective with respect to the visible light; an organic light emitting layer provided between the transparent electrode and the metal electrode and configured to emit white color light including two peaks, wherein each of the two peaks corresponds to a different wavelength component of the visible light; and an intermediate layer contacting the metal electrode and the organic light emitting layer between the organic light emitting layer and the metal electrode and transmissive with respect to the visible light, a thickness of the intermediate layer being 60 nanometers or more and less than 200 nanometers, and a refractive index of the organic light emitting layer to the visible light being higher than a refractive index of the intermediate layer to the visible light, wherein a refractive index of the organic light emitting layer is higher than a refractive index of the intermediate layer for each of the different wavelengths corresponding to each of the two peaks.
