PROBLEM TO BE SOLVED: To provide an antireflection film having a good antistatic property, transparency, scratch resistance and an antireflection property and suppressing generation of interference fringes.SOLUTION: An antireflection film comprises a polyester film having an easy-adhesion layer, and a hard coat layer and a low refractive index layer in this order on the easy-adhesion layer. The hard coat layer contains a compound having a quaternary ammonium base; the low refractive index layer contains inorganic fine particles and a polysiloxane compound having an ethylenically unsaturated group, each by the following content; and refractive indices of the easy-adhesion layer, the hard coat layer and the low refractive index layer are in the following ranges. The content of the inorganic fine particles is 40 mass% or more and less than 60 mass% with respect to 100 mass% of the total solid content of the low refractive index layer; and the content of the polysiloxane compound having an ethylenically unsaturated group is 1.5 mass% or more and less than 10 mass% with respect to 100 mass% of the total solid content of the low refractive index layer. The easy-adhesion layer has a refractive index of 1.55 or more and less than 1.61; the hard coat layer has a refractive index of 1.50 or more and less than 1.55; and the low refractive index layer has a refractive index of less than 1.40. |
