Problems solved by technology
However, when filming glass substrates used in these electronic devices, since glass is a brittle material, breakage occurs due to slight stress changes, and it is very difficult to handle the above-mentioned various processes related to the manufacture of electronic devices. The problem
In addition, glass films with a thickness of 200 μm or less are excellent in flexibility, so there are also problems such as difficulty in positioning during processing, and misalignment during patterning.

Abstract
A method of producing a glass film comprises a first step of forming an inorganic thin film on a surface of a supporting glass so that a surface of the inorganic thin film after being formed has a surface roughness Ra of 2.0 nm or less after film formation, a second step of forming a glass film laminate by laminating a glass film having a surface roughness Ra of 2.0 nm or less on the surface of the inorganic thin film in a state of being in contact with each other, a third step of carrying out treatment involving heating with respect to the glass film laminate, and a fourth step of peeling off the glass film from the supporting glass after the treatment involving heating.
Description
technical field [0001] The present invention relates to flat panel displays such as liquid crystal displays and organic EL displays, glass substrates for devices such as solar cells, lithium-ion batteries, digital signboards, touch panels, and electronic paper, and protective glasses for devices such as organic EL lighting and pharmaceutical packaging. A method for producing a glass film to be used, and a glass film laminate supported by a supporting glass. Background technique [0002] From the viewpoint of space saving, in recent years, flat panel displays such as liquid crystal displays, plasma displays, organic EL displays, and field emission displays have been popularized instead of conventionally popular CRT displays. In these flat panel displays, further thinning is required. Especially in an organic EL display, it is required to be able to use not only a flat surface but also a curved surface while being easy to carry by folding or winding. In addition, it is not l...
