Patent ID: 8507928

Claim:
An organic Electroluminescent (EL) device comprising: a first organic EL element, a second organic EL element, and a third organic EL element of different luminescent colors disposed adjacent to each other on an underlying layer including a substrate, the underlying layer including a first drive circuit unit for driving the first organic EL element, a second drive circuit unit for driving the second organic EL element, and a third drive circuit unit for driving the third organic EL element; and a partition defining a first film-forming region, a second film-forming region, and a third film-forming region on the underlying layer, the first film-forming region including a first light-emitting layer of the first organic EL element, the second film-forming region including a second light-emitting layer of the second organic EL element, and the third film-forming region including a third light-emitting layer of the third organic EL element, the partition defining the first film-forming region such that the first film-forming region includes the first drive circuit unit, the second film-forming region such that the second film-forming region does not include at least part of the second drive circuit unit, and the third film-forming region such that the third film-forming region does not include at least part of the third drive circuit unit, each of the first drive circuit unit, the second drive circuit unit, and the third drive circuit unit including a thin-film transistor, a retention capacitor, and a line connected between the thin-film transistor and the retention capacitor, the partition defining the second film-forming region and the third film-forming region such that the second film-forming region and the third film-forming region do not include at least the thin-film transistor, and the first light-emitting layer being formed by a different method from that used for the second light-emitting layer and the third light-emitting layer.
