Abstract:
The present invention provides an anti-glare film which has sufficient anti-reflection properties, a high level of contrast and strong antifouling properties. A surface of an anti-glare layer of the anti-glare film of the present invention has a concave-convex structure, an arithmetic mean roughness (Ra) according to JIS B0601-1994 in the range of 0.02-0.2 μm when a cut-off wavelength (λc) is 0.8 mm, and a surface free energy in the range of 15-25 mN/m. In addition, a haze of the anti-glare layer of the anti-glare film of the present invention is in the range of 1.0-5.0%.
