An organic electroluminescent element includes an organic layer including a compound having an electron donor moiety and an electron acceptor moiety in a single molecule. The compound satisfies the following expression: (ΔE
H
+ΔE
L
)≧2.0 eV. ΔE
H
represents a difference in energy level between a highest energy occupied molecular orbital spreading over the electron donor moiety and a highest energy occupied molecular orbital spreading over the electron acceptor moiety, and ΔE
L
represents a difference in energy level between a lowest energy unoccupied molecular orbital spreading over the electron donor moiety and a lowest energy unoccupied molecular orbital spreading over the electron acceptor moiety, determined by molecular orbital calculation. A highest energy occupied molecular orbital of the compound has an energy level of −5.2 eV or more. A lowest energy unoccupied molecular orbital of the compound has an energy level of −1.2 eV or less.
