Document Type and Number:
WIPO Patent Application WO/2015/080279
Kind Code:
A1
Abstract:
Provided is an antiglare film that has excellent antiglare properties at a wide observation angle even with a low haze, and that can sufficiently suppress the occurrence of white turbidity and glare when arranged on an image display device. This antiglare film comprises a transparent support body, and an antiglare layer formed thereon and having fine surface irregularities, wherein: the total haze is from 0.1% to 3% inclusive; the surface haze is from 0.1% to 2% inclusive; with respect to light that is incident at an incident angle of 30°, the ratio R(40)/R(30) between the reflectance R(30) at a reflection angle of 30° and the reflectance R(40) at a reflection angle of 40° is from 0.00001 to 0.0025 inclusive; and intensities I (0.01), I (0.02), and I (0.1) at a spatial frequency of 0.01 µm-1, a spatial frequency of 0.02 µm-1, and a spatial frequency of 0.1 µm-1, respectively, in a power spectrum of the height of said surface irregularities are within respective predetermined ranges.
