Abstract: Provided is an organic light emitting device with improved luminous efficiency and driving voltage. In the organic light emitting device, formation of a recombination zone inclining to an interface close to an electron transfer layer within an organic emission layer can be minimized. Thus, excitons are more likely to contribute to light emission without being lost. Therefore, luminous efficiency can be improved. Further, in the organic light emitting device, an energy barrier for electrons is minimized in an electron transfer route between the electron transfer layer and the organic emission layer. Therefore, a driving voltage can be improved.
