Abstract
An organic EL device including a first barrier film that contains primarily silicon nitride, a second barrier film that contains primarily silicon nitride, an organic EL element that is disposed between the first barrier film and the second barrier film, a first flexible substrate that is disposed opposite the organic EL element with the first barrier film interposed therebetween, a second flexible substrate that is disposed opposite the organic EL element with the second barrier film interposed therebetween, and a third barrier film that is disposed between the second barrier film and the organic EL element, and contains primarily silicon nitride.

An organic EL device comprising:
- a first barrier film that contains silicon nitride;
- a second barrier film that contains silicon nitride;
- an organic EL element that is disposed between the first barrier film and the second barrier film;
- a first flexible substrate that is disposed opposite the organic EL element with the first barrier film interposed therebetween;
- and
- a third barrier film that is disposed between the second barrier film and the organic EL element,
- wherein:
- the organic EL device has a bendable surface, each of the first barrier film, the second barrier film, the organic EL element, the first flexible substrate, and the third barrier film is bent along the bendable surface, and
- the bendable surface includes a longitudinal center of the organic EL device.
An organic EL device comprising:
- a first barrier film that contains silicon nitride;
- a second barrier film that contains silicon nitride;
- an organic EL element that is disposed between the first barrier film and the second barrier film;
- a first flexible substrate that is disposed opposite the organic EL element with the first barrier film interposed therebetween;
- and
- a third barrier film that is disposed between the second barrier film and the organic EL element,
- wherein a side end portion of the second barrier film and a side end portion of the third barrier film are located closer to the organic EL element than a side end portion of the first barrier film.
