Abstract:
A pressure-sensitive adhesive optical film of the present invention comprises: an optical film comprising a transparent base film and an optical compensation liquid crystal layer provided on one side of the transparent base film; a pressure-sensitive adhesive layer provided on the optical compensation liquid crystal layer; and an undercoat layer that is interposed between the optical compensation liquid crystal layer and the pressure-sensitive adhesive layer and contains a polymer and an antioxidant. The pressure-sensitive adhesive optical film can suppress window frame unevenness when a backlight is turned on.
