  • Patent number: 9684098
    Abstract: An antiglare hard coat film formed by providing an antiglare hard coat layer containing fine particles and a resin on a transparent film. When an average value of height in an evaluation region on a surface of the antiglare hard coat film is set at zero (0), a maximum cross sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is from 1.0 to 3.0 ?m, and an average inclination angle of unevenness on the surface of the antiglare hard coat film is 1 degree or less. The total value of the transmissive clarity measured through four optical combs using a transmissive clarity measuring device according to JIS K 7105-1981 is 280% or more, and the value of the transmissive clarity measured through each optical comb is 70% or more, respectively.
