POLARIZING FILM HAVING PRESSURE-SENSITIVE ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE

摘要

This polarizing film having a pressure-sensitive adhesive layer has a polarizing film and a pressure-sensitive adhesive layer provided on the polarizing film, The polarizing film has a transparent protective film on only one side of a polarizer. The pressure-sensitive adhesive layer is provided on the side of the polarizer which does not have the transparent protective film. The pressure-sensitive adhesive layer is formed from a pressure-sensitive adhesive composition that contains (A) a (meth)acrylic polymer, (B1) an onium-anion salt and (B2) an alkali metal salt. This polarizing film having a pressure-sensitive adhesive layer undergoes little deterioration in optical characteristics, and has a pressure-sensitive adhesive layer that, even after being subjected to a humidifying test under harsh conditions, has an anti-static function and satisfactory durability.
