ABSTRACT:
Provided is an organic electroluminescent device that brings together a high efficiency, high durability, and a high color purity. The organic electroluminescent device includes an anode, a cathode, and a layer including an organic compound interposed between the anode and the cathode, in which the layer contains at least one organic germanium compound having two or more fluorenyl groups per one germanium atom.
