Abstract
There is provided an optical body including: a base material; a second optical layer, formed on at least one surface of the base material, that reduces a reflection of extraneous light; and a first optical layer, laminated on top of a part of the second optical layer, that extracts internally propagating light incident inside the base material from a side face of the base material to an outside of the base material. On a surface of the first optical layer, a first concave-convex structure that reflects the internally propagating light is formed.
