Abstract

A sealing material is formed of a glass ribbon having a thickness of 1 to 100 μm. The sealing material has both surfaces and side surfaces formed into fire-polished surfaces.

First claim

The invention claimed is:

1. A flexible device comprising:
a plurality of glass substrates;
a sealing material, the sealing material being interposed between the glass substrates to seal a space between the glass substrates; and
one of an electrolyte, an element of a lighting device, an element of a solar cell device and an element of a display device sealed into the space,
wherein the sealing material is formed of a glass ribbon having a thickness of 1 to 100 μm, the sealing material having plain surfaces opposed to each other and side surfaces opposed to each other, each of the side surfaces comprising convex curved surface portions at corner portions that are continuous with the plain surfaces, a thickness deviation of the sealing material being within 20% of the thickness of the sealing material,
wherein each of the plain surfaces of the sealing material adheres to one of the glass substrates by thermal adhesion, and each of the side surfaces of the sealing material maintains the form of the convex curved surface portions,
wherein the sealing material has a film on at least one of the plain surfaces for absorbing a light having a predetermined wavelength, and
wherein the side surface of the sealing material are free of formation of the film.

2. The flexible device according to claim 1 , wherein each of the glass substrates has a thickness of 10 to 200 μm.

3. The flexible device according to claim 1 , wherein each the side surfaces including the convex curved surface portions is a fire-polished surface.

4. The flexible device according to claim 1 , wherein each of the plain surfaces is a fire-polished surface having a surface roughness Ra or 0.5 nm or less.

5. The flexible device according to claim 1 , wherein the sealing material has an aspect ratio of 25 to 2000 of width to thickness of the sealing material.

6. The flexible device according to claim 1 , wherein the sealing material contains a transition element.
