Abstract: There is provided a novel and improved optical body, method for manufacturing an optical body, light-emitting apparatus, and display apparatus for amusement equipment capable of improving emitted luminance and transparency, the optical body including: a base material; and a light extraction section, formed on at least one surface of the base material, that extracts internally propagated light incident inside the base material from a side face of the base material to an outside of the base material. The light extraction section includes a concave-convex structure in which at least one of concavities and convexities has a frustum shape, a fill ratio of the concave-convex structure is 15% or greater, and a light transmittance is 50% or greater.

Abstract: To form an optical body having a micro concave-convex structure on at least part of an adherend with high accuracy. Provided is an optical laminate including an adherend, a bonding layer formed on at least part of a surface of the adherend, and an optical body bonded to the adherend with the bonding layer. A micro concave-convex structure in which concavities and convexities are arranged at an average cycle less than or equal to a visible light wavelength is formed in at least one surface of the optical body. The bonding layer is provided on the other surface of the optical body. An initial 90° peeling force when peeling the optical body from a transfer body having an inverted concave-convex structure fitted in the micro concave-convex structure of the optical body is less than or equal to 70% of a 90° peeling force between the optical body and the bonding layer.
