Claim 0:
1. A light emitting device comprising:
a substrate;
a first electrode disposed on the substrate;
an organic material layer disposed on the first electrode and including a hole injection layer, a first resonance auxiliary layer, a first hole transport layer, and a light emitting layer; and
a second electrode disposed on the organic material layer,
wherein the first resonance auxiliary layer consisting of a single layer, and serves to adjust at least one of a distance between the light emitting layer included in the organic material layer and the first electrode and a distance between the light emitting layer and the second electrode,
wherein the first resonance auxiliary layer includes a first compound with a lowest unoccupied molecular orbital (LUMO) level of −4 eV or less and a second compound with a highest occupied molecular orbital (HOMO) level of −4 eV or less.
