Title:
POLARIZING FILM WITH ADDED ADHESIVE LAYER, POLARIZING FILM WITH ADDED ADHESIVE LAYER FOR IN-CELL LIQUID CRYSTAL PANEL, IN-CELL LIQUID CRYSTAL PANEL, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/181415
Kind Code:
A1
Abstract:
The present invention provides a polarizing film with added adhesive layer for realizing an in-cell liquid crystal panel which has excellent humidity resistance and in which the adhesion (keying) between the polarizing film and the adhesive layer is excellent, it is possible to prevent clouding attributable to the adhesive layer even in high humidity environments, and it is possible to satisfy a stable antistatic function and touch sensor sensitivity. This polarizing film with added adhesive layer is provided with an adhesive layer and a polarizing film, and is characterized in that: the adhesive layer is formed from an adhesive composition comprising an inorganic cation-anion salt and a (meth)acrylic polymer containing, as monomer units, alkyl (meth)acrylate and a polar functional group–containing monomer; and the ratio (b/a) of the variation in the adhesive layer–side surface resistances before and after humidification is no higher than 5.
