摘要： Disclosed is an organic electroluminescent device (organic EL device) that is improved in luminous efficiency, sufficiently secures driving stability, and has a simple configuration. This organic EL device comprises organic layers between an anode and a cathode piled one upon another on a substrate and at least one organic layer selected from a light-emitting layer, a hole-transporting layer, an electron-transporting layer, and a hole-blocking layer contains a carbazole compound represented by the following formula (1). In the case where the light-emitting layer of the organic electroluminescent device contains a phosphorescent dopant and a host material, it is the carbazole compound that is contained as the host material. In formula (1), X is C—Y or a nitrogen atom; Y is a hydrogen atom, an alkyl group, a cycloalkyl group, or an aromatic group; n is an integer of 2 to 4: A is an n-valent aromatic group; L is a direct bond or a divalent aromatic group; and R is a hydrogen atom, an alkyl group, or a cycloalkyl group.
