BASE FILM FOR LIQUID-CRYSTAL PANEL, FUNCTIONAL FILM FOR LIQUID-CRYSTAL PANEL, MANUFACTURING PROCESS FOR FUNCTIONAL FILM AND MANUFACTURING APPARATUS FOR FUNCTIONAL FILM

摘要

Conventional liquid crystal displays are large number of parts it is difficult to reduce the manufacturing cost. In addition, the substrate having a large area has had a problem in conveyance. ; According to the invention, a long film-like thin film, forming respective optical function film · TFT device, the light emitting device, a liquid crystal panel is produced by laminating the film by transfer. The base film to be the substrate of the liquid crystal panel has a thickness 10㎛ to 200㎛, the radius of curvature has a flexibility of less than 40㎜, it is preferable that the thermal expansion coefficient of not more than ± 50ppm / ℃. In addition, with respect to the heat history of at least 200 ℃, the change in the mechanical and optical characteristics is more preferably not more than ± 5%.
