Patent ID: 8513656

Claim:
An organic EL device comprising: a first organic EL element configured to comprise a first electrode on a substrate, a second electrode facing the first electrode, and a first emitting layer capable of emitting a first-colored light between the first and the second electrodes; a second organic EL element configured to comprise a third electrode on the substrate, a fourth electrode facing the third electrode, and a second emitting layer capable of emitting a second-colored light having a center wavelength longer than a center wavelength of the first-colored light between the third and the fourth electrodes, wherein at least a part of the first emitting layer extends on the second emitting layer; and a third organic EL element configured to comprise a fifth electrode on the substrate, a sixth electrode facing the fifth electrode, and a third emitting layer capable of emitting a third-colored light having a center wavelength longer than the center wavelength of the second-colored light between the fifth and the sixth electrodes, wherein at least a part of the first emitting layer and a part of the second emitting layers extend on the third emitting layer; wherein a thickness of the first emitting layer between the first and the second electrodes is thicker than a thickness of the first emitting layer extending on the second and the third emitting layers.
