PROBLEM TO BE SOLVED: To provide a method for producing a flat and highly productive anti-reflection film having excellent flatness, curling and curl, an anti-reflection film produced thereby, and polarized light using the anti-reflection film. Provide a board. SOLUTION: Atmospheric pressure plasma discharge treatment is carried out on a surface of a cellulose ester film containing an organic solvent-soluble additive, wherein at least one of the additives has a concentration gradient in the thickness direction, on the side with a high additive concentration. The antireflection film is manufactured by exposing the surface of the cellulose ester film to a reaction gas in a plasma state using an apparatus to form an antireflection layer. |
