<P>PROBLEM TO BE SOLVED: To provide an excellent protective film-fitted optical film, e.g., the protective film-fitted wide optical film with a width of ≥2m, in which separation voltage is hard to be caused when, after production of a polarizing plate, the protective film is interlayer-separated, adverse influence is hardly exerted to a liquid crystal element, and further, paste is not substantially left after the separation, and to provide a method for producing the same. <P>SOLUTION: In the protective film-fitted optical film obtained by laminating a protective film on at least one side of an optical film, an adhesion material layer is not substantially present in the boundary between the optical film and the protective film, and also, unevenness of thickness measured across the width direction of the optical film is ≤5%. <P>COPYRIGHT: (C)2010,JPO&INPIT |
