An organic electroluminescence (EL) element that has an anode; a cathode; an organic light-emitting layer between the anode and the cathode that emits light according to recombination of holes injected from the anode and electrons injected from the cathode; and an electron transport layer between the cathode and the organic light-emitting layer that transports electrons from the cathode to the organic light-emitting layer. The electron transport layer includes an n-type dopant that includes an electron-donating substance, the electron transport layer being doped with the n-type dopant at a doping concentration that is higher than a doping concentration at which light emittance efficiency of the organic light-emitting layer is greatest. |
