Abstract: Provided are a master in which a more complicated microstructure is formed, a transferred object obtained by using the master, and a method of producing the master. A plurality of concave-convex groups each including a plurality of concavities or convexities are provided on a base material apart from each other. Average widths of areas occupied by the concavities or convexities at a surface of the base material are smaller than or equal to a wavelength belonging to a visible light band. Formed lengths of the concavities or convexities from the surface of the base material in each of the concave-convex groups each belong to any of at least two or more groups having different central values.

Abstract: A replica master mold 10 comprises: a base material layer 11; and a surface shape body 12 formed on the base material layer 11 and having a fine irregular pattern, wherein a softening temperature of the surface shape body 12 is higher than a softening temperature of the base material layer 11.

Abstract: There is provided an optical body and a display device that enable wavelength dependence of a reflectance to be reduced and reflection of incident light to be further suppressed, the optical body including: a concave-convex structure formed on a surface of a base material. An average period of concavities and convexities of the concave-convex structure is equal to or shorter than a wavelength belonging to a visible light band. A standard deviation of differences between respective positions of bottom faces of the concavities of the concave-convex structure in a normal direction of a flat surface of the base material and a median of the positions of the bottom faces is greater than or equal to 25 nm.
