| 摘要 |
An organic electroluminescent device, comprising at least one organic compound layer containing a luminescent layer between a pair of electrodes, wherein the luminescent layer contains a fluorescence-emitting compound emitting fluorescence when voltage is applied thereto, the emission when voltage is applied is mainly derived from the fluorescence-emitting compound, and wherein the luminescent layer further comprises an amplifying agent functioning to increase the number of singlet excitons generated and thus amplifying the light intensity when voltage is applied, and the amplifying agent is a metal complex having a tridentate or higher ligand.
