    摘要： Provided is an organic electroluminescent device (organic EL device), in which the luminous efficiency of the device is improved, driving stability is sufficiently ensured, and the construction of the device is simple. This organic EL device is an organic electroluminescent device, including a light-emitting 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 as a host material. Examples of the indolocarbazole compound include a compound represented by the following formula (1). It should be noted that in the formulae: a ring A and a ring B are represented by the formulae (1a) and (1b), respectively; Ar's each represent an aromatic hydrocarbon group or an aromatic heterocyclic group; R's each represent a hydrogen atom, an alkyl group, or a cycloalkyl group; X represents a methine group or a nitrogen atom; A represents an aromatic hydrocarbon group, an alkyl group, a cycloalkyl group, or a group represented by the formula (1c); and n represents 0 or 1.

    摘要： 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.
