Abstract

See full text

There is provided a master, an optical body, and a master manufacturing method, including: forming, on a surface of a master body that includes a base material, a periodic micro concave-convex structure in which an average cycle of concavities and convexities is less than or equal to visible light wavelengths; forming an inorganic resist layer on the surface of the master body; microparticulating and spraying an organic resist dissolved in a diluent onto the inorganic resist layer, to thereby form an organic resist layer, on a surface of which is provided a macro concave-convex structure in which the average cycle of concavities and convexities is greater than the visible light wavelengths; and etching the organic resist layer, the inorganic resist layer, and the master body, to thereby superimpose and uniformly form the micro concave-convex structure and the macro concave-convex structure on the surface of the base material.
