Abstract
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.
