The present invention provides an organic electroluminescent device including an electron-leakage suppression layer and a hole-leakage suppression layer adjusted to have predetermined physical properties, in portions of a hole transporting area and an electron transporting area disposed on opposite sides of a light emitting layer, respectively, thereby reducing leakage of electrons and holes and thus improved in terms of characteristics such as a low driving voltage, high luminous efficiency, and long lifespan.

Organic electroluminescent device

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.
