ABSTRACT:
An organic EL device includes a cathode, organic luminescent layers, and an electron-injection layer disposed between the cathode and the luminescent layers. The electron-injection layer contains an organic metal complex having a central atom of the same metal element as a constituent element of the cathode. A larger number of ligands than the valence of the central atom of the complex are coordinated to the central atom.
