摘要
An optical body includes a first optical layer, a second optical layer having an incident surface on which light is incident, and a reflecting layer sandwiched between the first and second optical layers, wherein the first optical layer includes a plurality of convex or concave structures formed on or in a surface thereof on which the reflecting layer is disposed, ridges of the convex structures or ridges between the concave structures adjacent to each other have tip portions projecting toward the incident surface side, the tip portions are deformed from an ideal shape, the second optical layer is transparent and has a refractive index of 1.1 or more and 1.9 or less, and the optical body selectively directionally reflects part of light entering the incident surface, which part is in a specific wavelength band, in direction other than the specular reflection direction.
