Abstract:
1. An organic EL device comprising: a substrate; an array of electrodes including first and second electrodes and located above the substrate, top surfaces of the first and second electrodes having almost the same height; a counter electrode facing the array of electrodes; an organic layer including a first emitting layer interposed between the array of electrodes and the counter electrode and a second emitting layer interposed between the first emitting layer and the counter electrode, each of the first and second emitting layers being a continuous layer extending over a display region including the array of electrodes, a region of the first emitting layer corresponding to the second electrode being quenched, wherein portions of a laminate including 1) the array of electrodes, 2) the organic layer and 3) the counter electrode that correspond to the first and second electrodes form first and second organ EL elements different in luminous colors from each other; a reflective layer located between the substrate and the array of electrodes; and an adjustment layer having a light-transmitting property and located between the reflective layer and the first and second electrodes, wherein portions of the adjustment layer corresponding to the first and second electrodes have a thickness almost equal to a least common multiple of one-quarter a dominant wavelength of light emitted by the first emitting layer and one-quarter a dominant wavelength of light emitted by the second emitting layer.
