    摘要: An object of the present invention is to provide an optical film assured of reflectance low enough to suppress glaring and excellent in the scratch resistance, antifouling property and antistatic property, and another object is to provide a polarizing plate and a display, using such an antireflection film. These objects can be attained by an optical film, particularly, an antireflection film, containing a support and a thin film layer formed by coating a composition containing fine particles and a binder, in which the SP value ((B/A)×100)) which is a ratio of an average particle filling factor (B) in the region of 30% of the film thickness on the upper side opposite the support to an average particle filling factor (A) in the entirety of the thin film layer is 90% or less; and a polarizing plate and an image display, using the optical film.
