<P>PROBLEM TO BE SOLVED: To provide an antireflection film which is in contact with a conveyance roller at a state that the maximum surface becomes a high refractive index layer, with which a bright spot foreign matter is reduced even if winding is performed once, at a low cost and with low refractive index, a polarizing plate using the film and an image display device using the plate. <P>SOLUTION: In the antireflection film formed by applying a clear hard coat layer, a middle refractive index layer, the high refractive index layer and a low refractive index layer on a transparent supporting body, it is characterized that the high refractive index layer has a composition which uses titanium oxide particulates and a binder as main components, refractive index of 1.70 to 1.85 and film thickness of 40 to 70 nm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
