PURPOSE: To provide an optical film excellent in antireflection performance and scuffing and wear resistances at a low production cost. CONSTITUTION: The optical film is obtained by successively stacking (A) a hard coat layer containing an ionizing radiation curable resin and having 2-20 μm thickness, (B) a high refractive index layer I containing an ionizing radiation curable resin and a metal oxide and having a refractive index of 1.70-1.95 and 30-120 nm thickness, (C) a high refractive index layer II containing an ionizing radiation curable resin and a metal oxide and having a refractive index of 1.60-1.70 and 5-70 nm thickness and (D) a low refractive index layer containing a siloxane polymer and having a refractive index of 1.37-1.47 and 60-180 nm thickness on at least one face of a substrate film.
