Abstract
A method for producing a polarizing plate including a polarizer and a substrate film is provided. The method comprises: stretching a primary film to obtain a polarizer material film; providing an unstretched substrate film on the polarizer material film to obtain a layered body; and stretching the layered body to obtain the polarizing plate. The polarizer includes a dichroic material and has a thickness T of 20 μm or less. A phase difference Re in an in-plane direction of the substrate film in the polarizing plate is 20 nm or less.
