PROBLEM TO BE SOLVED: To provide a method of productively manufacturing a film that is thin and offers extremely small optical anisotropy and superior transparency and mechanical strength, a polarizing plate film obtained through the method, and a polarizing plate produced using the polarizing plate film.SOLUTION: A manufacturing method for a laminated thermoplastic resin film includes coextruding a layer (I) and a layer (II) containing different primary ingredients with the layer (II) placed on a face in contact with a nozzle, where the layer (I) and the layer (II) can be peeled from each other. After the layer (II) is peeled off, the layer (I) has a thickness of 50 μm or less, and in-plane retardation (R) and thickness retardation (R) of 10 nm or less.SELECTED DRAWING: None |
