<P>PROBLEM TO BE SOLVED: To provide an optical film, capable of preventing the hole opening or fracture upon formation of an emboss portion from occurring and fully preventing the films from being stuck to each other or from causing winding deviation upon wind-up. <P>SOLUTION: The optical film includes an optical thin-film layer 2 formed on one side surface 11 of a base film 1 and emboss portions 3, formed on both end portions in the film width direction WD of the other side surface 12 of the base film 1, wherein the optical thin-film layer 2 comprises a resin layer A having a softening point higher than the base film 1 and, when being observed from the film thickness direction AD, the resin layer A is formed so as to be superimposed, on at least emboss portion formation regions 50a, 50b on the emboss portion formation surface 12. <P>COPYRIGHT: (C)2011,JPO&INPIT |
