发明名称 METHOD FOR PRODUCING POLARIZING PLATE
摘要 <p>The present invention is a method for producing a polarizing plate, wherein: a polarizing film is produced by dyeing and crosslinking a polyvinyl alcohol film and then drying the polyvinyl alcohol film in a first drying step; and a polarizing plate is produced by carrying out a bonding step in which a laminate is formed by bonding a protective film on at least one surface of the polarizing film with an adhesive layer being interposed therebetween, and a second drying step in which the laminate is dried. The ratio of the thickness (Ta) of the polarizing film before the bonding step but after the first drying step to the thickness (Tb) of the polarizing film in the polarizing plate after the second drying step, namely Ta/Tb is from 1.02 to 1.30.</p>
