Organic electroluminescent device and electronic apparatus that can effectively release gas that is generated
An organic electroluminescent device includes a substrate; a plurality of light-emitting elements disposed on the substrate and including first transparent electrodes, a second transparent electrode, and light-emitting layers held therebetween; reflective layers disposed opposite the light-emitting layers with the first electrodes therebetween; a first insulating film disposed between the substrate and the reflective layers and formed of an organic material; and a second insulating film disposed between the first electrodes and the reflective layers so as to cover the reflective layers and the first insulating film. The second insulating film has a first through-hole at a position not overlapping the first electrodes in plan view. The first through-hole extends through the second insulating film to reach the first insulating film.
1. An organic electroluminescent device comprising:
a substrate;
a plurality of light-emitting elements disposed on the substrate and including first transparent electrodes, a second transparent electrode, and light-emitting layers held therebetween;
reflective layers disposed opposite the light-emitting layers with the first electrodes therebetween;
a first insulating film disposed between the substrate and the reflective layers and formed of an organic material; and
a second insulating film disposed between the first electrodes and the reflective layers so as to cover the reflective layers and the first insulating film, the second insulating film being formed of an inorganic material and the second insulating film having a first-through-hole at a position not overlapping the first electrodes in plan view, the first through-hole extending through the second insulating film to reach the first insulating film.
