Abstract
A glass film laminate includes a supporting glass and a glass film peelably laminated to the supporting glass. A contacting surface of the glass film and a contacting surface of the supporting glass directly contact each other without an adhesive therebetween. The contacting surface of the supporting glass includes a first region and a second region with a surface roughness smaller than a surface roughness of the first region. An adhesive force between the supporting glass and the glass film is greater at the second region than at the first region.
