摘要:
An antiglare film is provided and includes: a transparent support; and an antiglare layer containing a binder and a light-transmitting fine particle. The light-transmitting fine particle has an average particle diameter of 3 to 15 μm, the antiglare layer has an average thickness smaller than the average particle diameter of the light-transmitting fine particle by 0.1 to 2.0 μm, the antiglare layer contains the light-transmitting fine particle in an amount of 1.0 to 3.0 weight % based on all solid contents of the antiglare layer. The antiglare layer has a surface having a θ(1) of 60 to 98.5%, wherein the θ(1) is a ratio of a surface region of 0°≦θ≦1° in the surface when θ represents a tilt angle of an irregularity on the surface.
