Claim 13:
14. The light emitting device according to claim 6, wherein the organic material layer includes a first stack, a second stack, and a charge generation layer disposed between the first stack and the second stack,
wherein the first stack includes the first resonance auxiliary layer and the first light emitting layer and is disposed between the charge generation layer and the first electrode,
wherein the second stack includes a second resonance auxiliary layer and a second light emitting layer and is disposed between the charge generation layer and the second electrode, and
wherein the second resonance auxiliary layer includes a third compound with a lowest unoccupied molecular orbital (LUMO) level of −4 eV or less and a fourth compound with a highest occupied molecular orbital (HOMO) level of −4 eV or less,
wherein the thickness of the second resonance auxiliary layer is 20% to 90% of a total thickness of the organic material layer, and
wherein the second light emitting layer emits light having a wavelength of 550 nm to 700 nm.
