摘要：

A method for producing a polarizer of the present invention comprises: subjecting a polyvinyl alcohol film to at least a dyeing process, a crosslinking process and a stretching process; and then subjecting the polyvinyl alcohol film to a washing process with an aqueous solution containing 1 to 50% by weight of an alcohol and 0.5 to 10% by weight of an iodide compound. A polarizer produced by the production method has high transmittance and high degree of polarization.
