Abstract
The present invention discloses an organic electroluminescent (EL) device having improved luminous efficiency, sufficiently secured driving stability, and a simple construction. The organic EL device of the present invention includes, between an anode and a cathode laminated on a substrate, an organic layer including a material for a luminescent device, in which the material for a luminescent device includes a carborane compound. The carborane compound includes a branched carborane compound in which three or more carborane rings bonded to one another through an aromatic group are present, at least one dibenzothiophene ring is present, and the at least one dibenzothiophene ring is bonded to the carborane ring.
