Patent ID: 7212341

Claim:
An antireflection film comprising a transparent support, at least one high refractive index layer having a refractive index higher by 0.05 or greater but not greater than 1.5 than that of the transparent support, and a low refractive index layer having a refractive index lower by 0.05 or greater but not greater than 2.0 than that of the high refractive index layer, wherein the high refractive index layer comprises matting agent particles having an average particle size of 0.5 μm or greater but not greater than 5 μm, and inorganic fine particles having an average particle size of from 1 nm to 100 nm, wherein the inorganic fine particles are present in an amount of from 10% to 90% by mass based on the total mass of the high refractive index layer, the thickness of the high refractive index layer is 80% or greater but not greater than 120% of the average particle size of the matting agent particles, the center line average surface roughness on a surface of the antireflection film is 0.003 μm or greater but not greater than 0.10 μm, the film has a haze value of 10% or less, and the number of the matting agent particles which protrude from the high refractive index layer falls within a range of from 8000 particles/mm 2 or greater but not greater than 40000 particles/mm 2 .
