PROBLEM TO BE SOLVED: To constitute an organic EL element with the use of an organic phosphor for emitting light of a given luminous color at a high brightness and for easily obtaining a composition for application through solubilization or dispersion in forming a luminous layer. SOLUTION: A luminous layer using a matter expressed in a formula (1) as an organic phosphor is laminated together with another layer by pinching them with a pair of electrodes. Provided, in the formula (1), R and R' denote an alkyl group or an alkyl ether group and R and R' may be of the same functional group or of different functional groups. COPYRIGHT: (C)2004,JPO
