Abstract:
Disclosed are an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of driving stability, and simple in constitution and a compound for use therein. The organic electroluminescent device comprises a light-emitting layer disposed between an anode and a cathode piled one upon another on a substrate and the light-emitting layer contains a phosphorescent dopant and a compound for use in an organic electroluminescent device having two or more indolocarbazole skeletons as a host material. An example of the compound having indolocarbazole skeletons for use in the device is expressed by the following formula.
