摘要:
A light-polarizing plate for display use is improved in its humid, thermal and weather durabilities by controlling moisture content of a light-polarizing film made of polyvinylalcohol prior to be laminated with protector film and also by using as protector film a hydrophobic polymer film having low water vapor transmission.
