Abstract
A pressure-sensitive adhesive optical film of the invention comprises an optical film and a pressure-sensitive adhesive layer provided on the optical film, wherein the pressure-sensitive adhesive layer has a thickness (μm) standard deviation of 0.12 μm or less. The pressure-sensitive adhesive optical film makes it possible to reduce the problem of visible unevenness caused by a pressure-sensitive adhesive layer.
