A second compound containing a cathode, an anode, and an organic layer existing between the cathode and the anode, wherein the organic layer includes a fluorescent light emitting layer, and the fluorescent light emitting layer has a greater hole mobility than the first compound and the first compound. And an organic electroluminescent element containing a dopant material having a half-width of 30 nm or less in the fluorescence spectrum, and a cathode, an anode, and an organic layer existing between the cathode and the anode, wherein the organic layer includes a fluorescent light emitting layer, and the fluorescence The light emitting layer contains a first compound, a third compound having an affinity larger than the first compound, and a dopant material having a half width of 30 nm or less in the fluorescence spectrum, and the content of the third compound in the fluorescent light emitting layer is The organic electroluminescent device having less than the content in the fluorescent light emitting layer shows excellent performance. |
