See full text

A pressure-sensitive adhesive layer-attached polarizing film of the invention includes: a polarizing film; and a pressure-sensitive adhesive layer provided on the polarizing film, wherein the polarizing film includes a polarizer and a transparent protective film provided on only one side of the polarizer, the pressure-sensitive adhesive layer is provided on a side of the polarizer where the transparent protective film is absent, and the pressure-sensitive adhesive layer is made of a pressure-sensitive adhesive composition containing a (meth)acryl-based polymer (A) and an alkali metal salt (B). The pressure-sensitive adhesive layer-attached polarizing film has a pressure-sensitive adhesive layer with an antistatic function and satisfactory durability and whose optical properties are less likely to be degraded.
