Abstract
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.
