ABSTRACT:
An organic electroluminescence device includes: an emissive layer between an anode and a cathode facing each other; an anode buffer layer formed of a conductive material, installed between the anode and the emissive layer; a cathode buffer layer formed of the conductive material, installed between the cathode and the emissive layer; and a driving device which alternately applies a forward-biased voltage and a reverse-biased voltage which have different voltage values and polarities, to the anode and the cathode.
