Abstract: Antireflection coating on a substrate which is coated with a low refractive index layer having a specified refractive index which in turn is coated with a high refractive index layer having a higher refractive index than the low refractive index layer, is either characterized in that a roughened surface which scatters and reflects the incident light entered into the low refractive index layer in contact with the substrate is formed at the interface between the low refractive index layer and the substrate, or that a light-diffusing layer which scatters and reflects the incident light entered into the low refractive index layer in contact with the substrate is formed at the interface between the low refractive index layer and the substrate, or that a hard coating layer in contact with the low refractive index layer is formed by dispersing a light-diffusing material in the hard coating layer, which scatters and reflects the incident light entered into the low refractive index layer.
