Provided are a novel nitrogen-containing aromatic heterocyclic compound and an organic electronic device using the compound. Specifically provided is an organic electroluminescent device, including a plurality of organic layers between an anode and a cathode laminated on a substrate, in which at least one of the organic layers contains a nitrogen-containing aromatic compound represented by the following formula (1). In the formula, L represents an n+m-valent group arising from an alkane, a cycloalkane, an aromatic hydrocarbon, an aromatic heterocyclic compound, a triarylamine, or a diarylsulfone, A represents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, a silyl group, an acyl group, an aromatic hydrocarbon group, or an aromatic heterocyclic group, X represents C(R)2, oxygen, S, or Se, R represents H, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aromatic hydrocarbon group, or an aromatic heterocyclic group, m represents an integer of 1 to 4, and n represents an integer of 0 to 3. The total number of m and n is 2 to 4.
An organic electroluminescent device, comprising an anode, a plurality of organic layers, and a cathode laminated on a substrate, wherein at least one of the organic layers contains a compound represented by the general formula (1):
