According to one embodiment, an organic EL device includes a substrate, a first translucent insulating film, a second translucent insulating film, a first electrode, a second electrode, and an emitting layer. The substrate has a first index of refraction. The first translucent insulating film is on the substrate, and the first insulating film has a second index of refraction higher than the first index of refraction. The second translucent insulating film is on the first insulating film, and the second insulating film has a third index of refraction lower than the second index of refraction. The first electrode is on the second insulating film, and the first electrode has a fourth index of refraction higher than the third index of refraction. The second electrode is facing the first electrode. The emitting layer is between the first electrode and the second electrode. |
