A laminated film obtained by carrying out anti-reflection processing on the surface of a reflection polarizing film. This laminated film comprising (A) a monoaxially oriented laminated film consisting of 501 or more alternating first layers made of a first thermoplastic resin having a positive stress optical coefficient and a thickness of 0.05 to 0.5 μm and second layers made of a second thermoplastic resin different from the first thermoplastic resin and having a thickness of 0.05 to 0.5 μm, and a low-reflectance layer formed on at least one side of the monoaxially oriented laminated film and having a reflectance of the surface measured from the input side of 3% or less.
