PROBLEM TO BE SOLVED: To provide an optical film which has excellent MIT flex resistance while keeping heat resistance and transparency of an acrylic resin having a glass transition temperature of 120°C or higher.SOLUTION: An optical film contains (A) an acrylic resin having a glass transition temperature of 120°C or higher, and (B) an acrylic block copolymer formed of a polymer block (B1) containing a structural unit derived from acrylic ester and a polymer block (B2) containing a structural unit derived from methacrylate ester. In an MIT flex resistance test, both a longitudinal direction (MD) and a width direction (TD) of the optical film are 500 times or more, and an internal haze is 1.0% or less.SELECTED DRAWING: None |
