Abstract
An optical substrate such as a cover glass which effects only a small change in a reflected color dependent on an incident angle, or more particularly, an optical substrate such as a cover glass for displays includes a reinforcement layer intended to prevent cracking, an antiglare layer formed on the reinforcement layer, a tone-adjustment antireflection film formed on the antiglare layer, and an antifouling layer formed on the antireflection film intended to minimize fingerprint adhesion. The antireflection film includes at least nine layers.
