Title:
POLARIZATION PLATE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217535
Kind Code:
A1
Abstract:
This polarization plate comprises a polarizer, a protective film A having a water vapor permeability of 100 g/m2·24 hr or lower disposed on one of the surfaces thereof, a protective film B disposed on the other surface, and an adhesive layer disposed on the surface of the protective film B facing away from the polarizer. The protective film B contains a (meth)acrylic resin with a weight-average molecular weight of 500,000 or more and rubber particles, wherein the (meth)acrylic resin contains a structural unit derived from methyl methacrylate, and a structural unit derived from phenyl maleimide. The rubber particle content is 5 to 25% by mass relative to the protective film B. The protective film B further contains an aggregation inhibitor represented by formula (1).
