Abstract
An organic electroluminescent device is disclosed. The organic electroluminescent device achieves low driving voltage and high luminous efficiency as well as long lifespan by including an exciton confinement layer (ECL), in which a predetermined physical property is adjusted, in an area of an electron transporting area, including at least two layers, that is adjacent to an emissive layer.
