OPTICAL FILM, OPTICAL FILM MANUFACTURING METHOD, TRANSPARENT SUBSTRATE, IMAGE DISPLAY DEVICE, AND SOLAR CELL |
摘要 |
An optical film that is excellent not only in transparency and heat resistance but also in solubility in an organic solvent and linear thermal expansion coefficient. Also, a product or a member which meets high demands for heat resistance and low linear thermal expansion coefficient with the use of the optical film, more specifically a transparent substrate using the optical film, and an image display device and a solar cell including the optical film or the transparent substrate. The optical film contains a polyimide having a specific structure in which a repeating unit of a chain of a polymer has both an amide group and an imide group and the polymer has a fluorine atom. The polyimide is obtained by mixing a dehydrating agent and an imidizing agent with a polyamic acid solution so as to imidize the polyamic acid. |
