Abstract
A transparent substrate with an antiglare film, includes a transparent substrate having first and second main surfaces and an antiglare film formed on the first main surface. The antiglare film includes a low refractive index layer formed on the first main surface and a high refractive index layer formed in the low refractive index layer and having a refractive index different from that of the low refractive index layer. The low refractive index layer has nof 1.4 to 1.8. The high refractive index layer has nat least 0.1 higher than the n. The high refractive index layer has an area ratio of its portion where a surface inclination to the first main surface is 0.5° or less of 15% or less. An average length RSm of elements of a roughness curve of an outermost surface on a first main surface side is 50 μm or less.
