Patent ID: 7573191

Claim:
An organic EL device comprising: a substrate a light-reflective electrode; a first light-transmissive electrode and a second light-transmissive electrode between the substrate and the light-reflective electrode; a first organic EL layer between the light-reflective electrode and the first light-transmissive electrode, the first organic EL layer being made of an organic EL material to emit a first color light; a second organic EL layer between the light-reflective electrode and the second light-transmissive electrode, the second organic EL layer being made of an organic EL material to emit a second color light different from the first color light; a first transflective layer between the first light-transmissive electrode and the substrate to reflect a part of the first color light and transmit a part of the first color light; and a second transflective layer between the second light-transmissive electrode and the substrate to reflect a part of the second color light and to transmit a part of the second color light, the first transflective layer having a different occupation area than an occupation area of the second transflective layer in plan view.
