<P>PROBLEM TO BE SOLVED: To provide light diffusing film being better in optical isotropy, having high planarity, smooth surface, also few curl, favorable surface quality and high productivity in the light diffusing film employing in transmission type screens or the backlight of liquid crystal displays, illuminating panels, touch panels and the like. <P>SOLUTION: In the method for manufacturing the light diffusing film with the haze of ≥30% by employing at least two or more kinds of dopes, which are simultaneously or successively cast on a support, and being dried after separation, the light diffusing film contains cellulose ester and, at the same time, the employed dopes consist of one or more kind of dope forming the surface layer of the film and at least one or more kinds of dope forming the internal region of the film under the condition that at least one dope forming the internal region contains fine particles. <P>COPYRIGHT: (C)2011,JPO&INPIT |
