Abstract
An organic light emitting device is described. The organic light emitting device includes: a substrate; a first electrode on the substrate; an emission layer on the first electrode; a second electrode on the emission layer; and an exciton blocking layer between the first electrode and the emission layer, in which a LUMO energy level of the exciton blocking layer is higher than a LUMO energy level of the emission layer.
