ANTIREFLECTION FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE

摘要

The present invention can provide an antireflection film improved in the scratch resistance while having a sufficiently high antireflection property, and a polarizing plate and a display device using the antireflection film. The antireflection film comprises a transparent support, and as an outermost layer, a low refractive index layer containing a fluorine-containing polymer. The low refractive index layer comprises at least one inorganic fine particle having an average particle size of 30 to 100% of the thickness of the low refractive index layer. The inorganic particle is a silica fine particle, and at least one of the silica fine particles in the low refractive index layer is a hollow silica fine particle having a refractive index of from 1.17 to 1.40. Moreover, the hollow silica fine particle comprises an outer shell and a single vacancy inside the particle, and a porosity of the hollow silica fine particle defined by formula (VIII) is from 10 to 60%: x = 4 �¢ À �¢ a 3 / 3 / 4 �¢ À �¢ b 3 / 3 × 100 wherein a is a radius of the vacancy and b is the radius of the outer shell.
