CELLULOSE ACYLATE DOPE COMPOSITION, CELLULOSE ACYLATE FILM AND OPTICAL FILM AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cellulose acylate film having high transmittance and retardation stability for a temperature change, to provide a dope composition affording the film and to provide an optical film and a liquid crystal display device using the same film.

SOLUTION: The cellulose acylate dope composition comprises at least one kind of cellulose acylate and one or more kinds of photopolymerizable compounds photopolymerizable in the absence of a photopolymerization initiator. The cellulose acylate film is produced by a series of steps comprising a casting step of casting the composition and a light irradiating step. The optical film and liquid crystal display device are obtained by using the film.
