ABSTRACT:
The organic electroluminescent device of the present invention has at least one organic compound layer containing a light-emitting layer between an anode and a cathode. The organic compound layer contains a fluorescent light-emitting compound emitting fluorescence at a time that voltage is applied and an amplifying agent. A phosphorescent light-emitting maximum wavelength of the amplifying agent is 500 nm or less, and the light emission at a time that voltage is applied is derived mainly from light emission of a fluorescent compound. In order to amplify intensity of emission at a time that voltage is applied It is preferable that the amplifying agent be capable of amplifying the number of singlet excitons generated at a time that voltage is applied.
