Beschreibung
Zusammenfassung:	Provided are an optical functional film including at least one functional layer, where the functional layer comprises a copolymer having a polymerization unit derived from a fluoroaliphatic group-containing monomer in a content of 10 weight % or more and the fluoroaliphatic group-containing copolymer is localized on the surface of the functional layer; an optical functional film obtained by coating an upper layer on the functional layer; an antireflection film, where the upper layer is a low refractive index layer; a polarizing plate using such a film for one of two protective sheets of a polarizer; and an image display device using the above-described optical functional film, antireflection film or polarizing plate for the outermost surface of the display.
