摘要:
To provide an antireflection film that is excellent in color uniformity while suppressing the reflectance. An antireflection film containing a transparent substrate having thereon a high refractive index layer and a low refractive index layer, the antireflection film having a luminous reflectance Y value, which is measured with a specimen containing the antireflection film and a black board adhered on a side of the transparent substrate opposite to the high refractive index layer through a transparent adhesive, that satisfies the following condition (1), and an a* value and a b* value of the Lab color coordinate system, which are measured with the specimen, that satisfy the particular condition: assuming that an incident angle of light incident perpendicularly on a surface of the specimen on a side of the low refractive index layer is 0 degree, when light is made incident on the specimen at an incident angle of 5 degrees, specularly reflected light of the incident light has a luminous reflectance Y value of 0.50% or less.
