摘要 |
An optical body includes a first optical layer having a concave-convex surface, a wavelength selective reflecting layer formed on the concave-convex surface, and a second optical layer formed on the wavelength selective reflecting layer and embedding the concave-convex surface. The wavelength selective reflecting layer selectively directionally reflects light in a particular wavelength band while transmitting light other than the particular wavelength band therethrough. The concave-convex surface is made up of a plurality of triangular pillars arrayed in a one-dimensional pattern, and the triangular pillar has an apex angle ± and a slope angle ², the apex angle ± and the slope angle ² satisfying a predetermined relationship. |
