Abstract: Organic electroluminescent devices are provided. The organic electroluminescent device may includes a first light emitting part including a transparent first electrode, a first organic light emitting layer, and a transparent second electrode which are stacked, and a capping layer stacked on the first light emitting part. The first light emitting part emits light of a first wavelength, and the capping layer reflects the light of the first wavelength and transmits light of a second wavelength. Thus, the lights of the first and second wavelengths are emitted in high efficiency.
