Abstract: A curved substrate with a film includes a substrate having a first main surface, a second main surface and an end surface, and an antiglare film provided on the first main surface. The substrate has a flat portion and a bent portion. A value obtained by dividing a reflected-image diffusibility index value R of the bent portion by the sum of the reflected-image diffusibility index value R of the bent portion and a reflected-image diffusibility index value R of the flat portion is 0.3 or higher and 0.8 or less.

Abstract: The present invention provides a cover glass and a glass laminate which are reduced in warpage, and have excellent scratch resistance, low reflecting properties and excellent optical properties. According to the present invention, a cover glass and a glass laminate which are reduced in glass warpage, retain the effect of scratch resistance, and have low reflecting properties and excellent optical properties can be provided by alternately superposing a film including a high-refractive-index material and a film including a low-refractive-index material, in given amounts.

Abstract: To appropriately suppress reflection of far-infrared rays, and appropriately form an antireflection film. A far-infrared ray transmission member (20) includes a base material (30) that transmits far-infrared rays, and a functional film (32) that is formed on the base material (30) and includes a low refractive index layer (34) containing oxide as a principal component and having a refractive index equal to or smaller than 1.5 with respect to light at a wavelength of 10 μm. The low refractive index layer (34) contains MgO as a principal component, and a content of MgO is equal to or larger than 50 mass % and equal to or smaller than 100 mass % with respect to the entire low refractive index layer (34).
