ABSTRACT:
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 grating2on the surface of the substrate1and an organic EL layer5including an emission layer between an anode4an a cathode6via an intermediate layer3.
