Abstract: A method for evaluating a base material includes deforming a base material. The base material includes a bent portion, and includes a first main surface, a second main surface, and an end surface to change a curvature of the bent portion. The method further includes evaluating a surface state of the first main surface of the base material.

Abstract: A transparent substrate with a light-shielding layer, including: a transparent substrate including a first main surface and a second main surface; an infrared ray-transmitting layer that is disposed so as to be in contact with the first main surface of the transparent substrate, transmits an infrared ray, and shields a visible light; and a light-shielding layer that is disposed on the infrared ray-transmitting layer, includes an opening that exposes a part of the infrared ray-transmitting layer, and shields the visible light and the infrared ray, in which the light-shielding layer includes an end portion that projects from an end portion of the infrared ray-transmitting layer, that is closest to an outer circumference of the transparent substrate, and is in contact with an end face of the infrared ray-transmitting layer and the transparent substrate.

Abstract: The translucent structure of the present invention has a haze of higher than 10% and at most 70% and has a concavo-convex structure on its surface. The concavo-convex structure has first convex portions having a diameter of larger than 10 μm in a cross section at a height of 0.05 μm+the bearing height of a surface shape, and second convex portions having a diameter of larger than 1 μm in a cross section at a height of 0.5 μm+the bearing height. The average diameter of the first convex portions is larger than 10 μm and at most 185 μm in a cross section at a height of 0.05 μm+the bearing height. The maximum height of the first convex portions is from 0.2 to 8 μm. The number of the second convex portions is from 0.0004 to 1.2 per 1 um2.
