The antiglare film includes a low refractive index layer formed on the first main surface and a high refractive index layer formed in the low refractive index layer and having a refractive index different from that of the low refractive index layer. The low refractive index layer has nlow of 1.4 to 1.8. The high refractive index layer has nhigh at least 0.1 higher than the nlow. The high refractive index layer has an area ratio of its portion where a surface inclination to the first main surface is 0.5° or less of 15% or less. An average length RSm of elements of a roughness curve of an outermost surface on a first main surface side is 50 μm or less.

Abstract: A near-infrared cut filter has a transparent substrate and an optical multilayer film formed on the transparent substrate and including high-refractive index films each having a refractive index at a wavelength of 500 nm in a range of 2.0 to 2.8 and low-refractive index films each having a refractive index at the wavelength of 500 nm of less than 1.6. The multilayer film is formed such that the high-refractive and low-refractive index films are alternately stacked and that the filter has spectral transmittance characteristic for the entire wavelength range of 450 nm to less than 550 nm and part of that wavelength range for incident light having incident angle of 0 degree, and part of wavelength range of 450 nm to less than 550 nm and the entire wavelength range of 450 nm to less than 550 nm for incident light having incident angle of 40 degrees.
