The degree of polarization of the invention provides a method for producing superior multilayer films.
One aspect of the production method of the multilayer film of the present invention, the second measuring step a first measuring step of measuring the angle of the absorption axis of the polarizer and, for measuring the angle of the fast axis of the retardation film in the predetermined direction, the absorption axis and the fact-axis relative angle is less than a predetermined angle, and includes a retardation film bonding step of bonding the bonding surface of the retardation film and the selection process of selecting the joint surfaces, which are mutually joined from the polarizing film and phase difference film, the bonding surface of the polarizing film in the above retardation film bonding step, to the longitudinal direction of the retardation film and the longitudinal direction of the polarizing films aligned, characterized by bonding the retardation film on the polarizing film.
