摘要:
The present invention relates to a method for manufacturing a polarizer, including: a) immersing and swelling a polyvinyl alcohol-based film in an aqueous solution containing an azo-based dye having an absorption wavelength of 300 nm to 550 nm; b) dyeing the swollen polyvinyl alcohol-based film with an iodine-based dye; and c) stretching the dyed polyvinyl alcohol-based film, and a polarizer manufactured using the method.
