ABSTRACT:
On a cathode (40) of an organic EL element, a stress reducing layer (42) formed by a material which is the same as that used for an organic layer of the organic EL element is formed. A moisture block layer (44) formed by a material which is the same as that used for the cathode (40) is then formed on the stress reducing layer (42). Thus, entering of moisture is effective prevented while the stress is reduced.
