<P>PROBLEM TO BE SOLVED: To provide an organic EL device with a superior service life characteristic, and an organic EL display. <P>SOLUTION: The organic EL device 30 is provided with an anode 31, a cathode 32 facing the anode 31, and an organic layer 33 interposed between the anode 31 and the cathode 32 and including a light emitting layer. It is characterized by that the cathode 32 is provided with a protective conductor layer 32b facing the organic layer 33, a main conductor layer 32a interposed between the protective conductor layer 32b and the organic layer 33 and comprising a material that is different from a material of the protective conductor layer 32b, and an outer barrier layer 32d interposed between the protective conductor layer 32b and the main conductor layer 32a to suppress diffusion of constituent elements of the protective conductor layer 32b into the main conductor layer 32a. <P>COPYRIGHT: (C)2004,JPO |
