This invention provides a method for manufacturing a polarizing multilayer film, said method including the following steps: a step in which a polyvinyl-alcohol-resin layer is formed on the surface of a base film, yielding a multilayer film; a step in which said multilayer film is stretched, yielding a stretched film; and a step in which a dichroic pigment is used to dye the polyvinyl-alcohol-resin layer of the stretched film so as to make said layer into a polarizer layer, yielding a polarizing multilayer film. The arithmetic average roughness (Ra0) of the surface of the base film on which the polyvinyl-alcohol-resin layer is formed is less than or equal to 130 nm. This invention also provides a method for manufacturing a polarizing plate, said method including the following steps, in this order: a step in which a first protective film is affixed to the surface of the polarizer layer in the obtained polarizing multilayer film that faces away from the base film; and a step in which the base film is peeled off. |
