Abstract
A antiglare layer having a fine uneven surface is formed directly or through other layer(s) on a transparent substrate film and a layer having a low refractive index, which is lower than the refractive index of the antiglare layer is formed thereon. The refractive index of the antiglare layer is higher than the refractive index of a layer in contact with said antiglare layer on its surface remote from the layer having a low refractive index. An SiO film may be used as the layer having a low refractive index. The SiO film per se has excellent gas barrier property and antifouling property as an optical functional membrane and is an optical functional material characterized by having excellent moistureproofness, scratch resistance, adhesion to a substrate, transparency, low refractive index, dye deterioration preventive property, and other properties.
