  • Publication number: 20120001165
    Abstract: Provided is an organic electroluminescent device (organic EL device), which has improved luminous efficiency, has sufficient driving stability, and has a simple construction. The organic EL device of the present invention is an organic electroluminescent device, including a light-emitting layer and a hole-transporting layer between an anode and a cathode laminated on a substrate, in which the light-emitting layer contains a phosphorescent light-emitting dopant and an indolocarbazole compound that serves as a host material, or alternatively, the hole-transporting layer contains an indolocarbazole compound. The indolocarbazole compound is represented by the following formula (1). In the formula: A1's each represent an aromatic hydrocarbon group or an aromatic heterocyclic group, provided that at least one of A1's has a fused ring structure; and R1's each represent a hydrogen atom, an alkyl group, an alkoxy group, or an acyl group.
