摘要： A method for producing a laminated optical film that allows three-dimensional images to be reproduced, which is preferably used in a large image display apparatus. One embodiment of the method includes laminating a polarizing plate and a λ/4 plate and forming a λ/2 layer partially on the λ/4 plate. The polarizing plate and the λ/4 plate are laminated such that an angle between an absorption axis of a polarizer of the polarizing plate and a slow axis of the λ/4 plate is substantially 45°, and the λ/2 layer is formed such that an angle between the absorption axis of the polarizer and a slow axis of the λ/2 layer is substantially 45°.
