摘要 |
Disclosed is an organic electroluminescent device having high external quantum efficiency and long life. Also disclosed are an illuminating device and a display device. The organic electroluminescent device is characterized by containing at least one compound having a partial structure represented by the following general formula (1). [chemical formula 1] (1) In the formula, R1 represents a group (preferably an aromatic hydrocarbon group, an aromatic heterocyclic group, an alkyl group or an alkoxy group) having 4-20 carbon atoms in total and a substituent having a formula weight of 70-350 (preferably an alkyl group or an alkoxy group); R2-R4 independently represent a substituent; n2 represents a number of 0-4; n3 represents a number of 0-2; n4 represents a number of 0-8; and Q represents an atomic group necessary for forming an aromatic hydrocarbon ring or an aromatic heterocyclic ring. |
