Abstract
A method for manufacturing a polarizing plate comprising a polarizing film and a transparent protective film provided on at least one surface of the polarizing film, the method comprising the steps of: subjecting at least a surface of the transparent protective film to be bonded to the polarizing film to an adhesion improving treatment; bringing water into contact with at least the surface subjected to the adhesion improving treatment; and laminating the transparent protective film on the polarizing film so that the surface subjected to the adhesion improving treatment and brought into contact with water is bonded to the polarizing film.
