摘要：
A fluorine-containing copolymer of the following formula. A film-forming composition containing the copolymer. An anti-reflection film having a low-refractive-index layer containing the copolymer. An anti-reflection film having the above anti-reflection film on a transparent support. An image display device having the anti-reflection film. formula In the formula, Rf1 represents a specific fluorine-containing alkyl group; Rf2 represents a specific perfluoroalkyl group; A represents a constituent having at least one reactive group capable of contributing to a cross-linking reaction; B represents an arbitrary constituent; a to d each represent a mole fraction (%) of each constituent, which satisfy the following conditions: 55≦a+b≦95, 5≦a≦90, 5≦b≦70, 5≦c≦45, 0≦d≦40
