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.

Antiglare film having specified surface roughness and surface inclination

A transparent substrate with a laminated film, which comprises a transparent substrate and a laminated film formed on at least one surface of the transparent substrate, wherein the laminated film has a first dielectric layer, a crystallinity-improving layer, a functional layer and a second dielectric layer in this order from the transparent substrate side, the crystallinity-improving layer contains ZrN(wherein x is higher than 1.2 and at most 2.0), the functional layer contains at least one metal nitride selected from the group consisting of titanium nitride, chromium nitride, niobium nitride, molybdenum nitride and hafnium nitride, and the concentration of oxygen atoms at a boundary between the crystallinity-improving layer and the functional layer, is at most 20 atom %.

Transparent substrate with laminated film

The present invention relates to a translucent structure having a surface unevenness shape which has: an area ratio of surface flat regions in which an angle formed with a flat surface is in a range of 0&#xb0; to 0.5&#xb0; of in a range of 0% to 5.8%; a projection density of in a range of 0.0001/&#x3bc;mto 0.05/&#x3bc;m; a projection area ratio of in a range of 5.5% to 50%; a skewness Ssk which represents the degree of non-symmetry of in a range of &#x2212;0.5 to 1.1; a load area factor Smr1 at a boundary between a projected mountain portion and a core portion of in a range of 0% to 14.5%; and an arithmetic average surface roughness Sa of in a range of 0.06 &#x3bc;m to 0.143 &#x3bc;m.
