Abstract:
A layered body including a polarizer material film that is a product of stretching in one or more directions, and a substrate film provided on the polarizer material film, the substrate film being a product of stretching in one or more directions, wherein a stretching ratio X of the polarizer material film is 1.5 or more and 5.5 or less, a thickness T2 is 20 μm or less, the thickness T2 being a thickness of the polarizer material film as a result of free end uniaxial stretching of the layered body at a stretching ratio 6.0/X, an angle θ2 formed by a stretching direction of the polarizer material film and a stretching direction of the substrate film is less than 1°, and a stretching ratio Y of the substrate film is smaller than the stretching ratio X of the polarizer material film.
