1. An antiglare film comprising:
a transparent substrate; and
an antiglare layer including a binder matrix and a particle, on the transparent substrate;
wherein center line average roughness Ra of a surface of the antiglare film which surface is on the antiglare layer side among both sides of the antiglare film is 0.06-0.17 μm,
wherein reflectivity of 5° angle of the surface is 2.4-4.4%,
and wherein difference in refractive index between the binder matrix and the particle is equal to or less than 0.07.
