ABSTRACT:
An organic electroluminescence (EL) device which has a rear substrate, an organic EL element formed on the rear substrate and having a laminate structure in which a first electrode, an organic layer and a second electrode are sequentially laminated, a front substrate coupled to the rear substrate via sealant to seal an internal space in which the organic EL element is accommodated, and a transparent nanoporous oxide layer having nanoporous oxide particles disposed in the internal space formed by the rear substrate and the front substrate. Since the organic electroluminescence device includes the transparent nanoporous oxide layer having the nanoporous oxide particles and pores, it has an improved lifetime by increased moisture and oxygen absorbing properties.
