WIPO Patent Application WO/2022/172755
Kind Code:
A1
Abstract:
[Problem] To provide a novel polarizing plate that inhibits a poor external appearance of a polarizing film due to thermal contraction, and that excels in durability. [Solution] This polarizing plate comprises a polarizing film composed of a polyvinyl alcohol–based resin, and a supporting base material layered on at least one of the surfaces of the polarizing film with a bonding layer therebetween, said supporting base material being light-transmitting, and is characterized in that the bonding layer is composed of a molecular bonding agent that binds the polarizing film and the supporting base material together via a chemical bond.
