Abstract

A glass film laminate includes a supporting member and a glass film laminated to each other. The supporting member protrudes from the glass film, and has a peeling start portion at which at least one corner portion of the glass film is exposed from the supporting member. The peeling start portion is provided with a distance from a side of the supporting member.

First claim

The invention claimed is:

1. A glass film laminate, comprising a supporting member and a glass film laminated to each other, wherein:
the supporting member is a supporting glass and protrudes from an entirety of all sides of a surface of the glass film facing the supporting member;
the supporting member comprises a thin portion at which a thickness of the supporting member is partially reduced, the thin portion being provided at a side portion of the supporting member and extending to an edge of the supporting member;
the glass film and the supporting member adhere to each other; and
at least a part of a side of the glass film overlaps the thin portion of the supporting member and is distanced from the thin portion of the supporting member with a distance of greater than or equal to 0.01 mm, the at least the part of the side of the glass film being a portion from which the glass film is peelable off the supporting member.

2. The glass film laminate according to claim 1 , wherein the thin portion is provided so that at least one corner portion of the glass film is distanced from the supporting member.

3. The glass film laminate according to claim 1 , wherein the glass film is distanced from the supporting member within a width of 0.5 to 15 mm from the side of the glass film.

4. The glass film laminate according to claim 1 , wherein the glass film has a thickness of 300 μm or less.

5. The glass film laminate according to claim 2 , wherein the glass film has a thickness of 300 μm or less.

6. The glass film laminate according to claim 3 , wherein the glass film has a thickness of 300 μm or less.

7. The glass film laminate according to claim 1 , wherein each of the supporting member and the glass film is rectangular.
