Abstract
Provided is a transparent conductive film-attached glass sheet that is less likely to be broken when produced or used in the form of a roll. A transparent conductive film-attached glass sheet 1 includes: a glass sheet 2; and an amorphous transparent conductive film 3 provided on a principal surface 2a of the glass sheet 2.
Claims3
A transparent conductive film-attached glass roll comprising:
- a transparent conductive film-attached glass sheet taken up into a roll, the transparent conductive film-attached glass sheet including:
- a glass sheet;
- and
- an amorphous transparent conductive film provided on a principal surface of the glass sheet;
- wherein
- the glass sheet has a thickness of not less than 10 μm and not more than 200 μm;
- the transparent conductive film is made of indium zinc oxide;
- and
- when the transparent conductive film-attached glass sheet is cut into 100 mm square pieces to obtain a transparent conductive film-attached glass sheet sample, and the transparent conductive film-attached glass sheet sample is put on a flat plate, and respective distances x1 to x4 from four ends of the transparent conductive film-attached glass sheet sample to the flat plate are measured, an amount of warpage corresponding to an average of distances x1 to x4 ((x1+x2+x3+x4)/4) is less than 1 mm.
