A cathode, an anode, and an organic layer present between the cathode and the anode, wherein the organic layer includes a fluorescent light-emitting layer, the fluorescent light-emitting layer is a first compound, and holes larger than the first compound. A second compound having mobility, and an organic electroluminescence device containing a dopant material having a half-width of a fluorescence spectrum of 30 nm or less, and a cathode, an anode, and an organic layer present between the cathode and the anode. The organic layer includes a fluorescent light-emitting layer, and the fluorescent light-emitting layer includes a first compound, a third compound having a higher affinity than the first compound, and a dopant material having a half-width of a fluorescent spectrum of 30 nm or less. In addition, the organic electroluminescence device in which the content of the third compound in the fluorescent light emitting layer is smaller than the content of the first compound in the fluorescent light emitting layer exhibits excellent performance. |
