摘要:
An antireflection film is formed by alternately laminating a low refractive index layer and a high refractive index layer. The antireflection film has a reflectance of 10% or less and an excitation purity range of 10% or less for visible light in a wavelength range from 380 nm to 780 nm incident at an incident angle ranging from 0° to 45° when regarding the direction perpendicular to the surface as 0°. The antireflection film inhibits a specific color tone from occurring in interference color of incident light coming from an oblique direction.
