Beschreibung
Zusammenfassung:	The present invention relates to an organic electroluminescent device. There is provided an organic electroluminescent device with a good luminescence property and high luminous efficiency in which the organic electroluminescent device has a diffraction grating 2 on the surface of the substrate 1 and an organic EL layer 5 including an emission layer between an anode 4 an a cathode 6 via an intermediate layer 3.
