Antireflection film, and image display device

An image display device, which comprises, on an image display surface thereof, an antireflection film comprising a transparent support, at least one high refractive index layer having a refractive index higher by 0.05 or greater than that of the transparent support and a low refractive index layer having a refractive index lower by 0.05 or greater 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/mm2 or greater but not greater than 40000 particles/mm2.
