Organic EL device, method for manufacturing organic EL device, and electronic device

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.
