ABSTRACT:
An organic EL device comprises a plurality of organic EL elements, each of which has a pair of electrodes and functional layers including at least a light-emitting layer between the electrodes. With respect to components other than the light-emitting layer, the structure of the functional layer in one organic EL element among the organic EL elements is different from those of the functional layers in other organic EL elements.
