TRANSPARENT FILM, TRANSPARENT ELECTROCONDUCTIVE FILM, LIQUID CRYSTAL DISPLAY, ORGANIC EL DISPLAY, TOUCH PANEL AND METHOD FOR PRODUCING THE TRANSPARENT FILM

摘要

PROBLEM TO BE SOLVED: To provide a transparent film useful for a liquid crystal display, an organic EL display or a touch panel as a substrate having high transparency and heat resistance, a small birefringence and a positive wavelength dispersion of the birefringence. SOLUTION: The transparent film is characterized in that a cross-linked polymer material obtained by polymerizing and cross-linking polysaccharides substituted with a functional group having a polymerizable unsaturated double bond with an organometallic compound represented by formula (1) (V-L)nM(OR)m-n(wherein, M denotes a metal atom; m denotes the valence of the metal atom M; V denotes the functional group having the polymerizable unsaturated double bond; L denotes a bivalent linking group linking V to M; R denotes a hydrogen atom or an alkyl group; and n denotes a positive integer of≥1 to
