1. A display, comprising:
a periodic structure that is dielectric and includes a support and a plurality of periodic elements, the support having a reference plane on which the plurality of periodic elements are arranged in a two-dimensional lattice form having a sub-wavelength period, the plurality of periodic elements being either convexities projected from the reference plane or concavities recessed in the reference plane; and,
a metal layer disposed on a surface of the periodic structure, the surface corresponding to a plane including a region of the reference plane surrounding the individual periodic elements and surfaces of the periodic elements, the metal layer having a profile conforming to a surface profile of the periodic structure, wherein
each of the periodic elements is a polygon in plan view, wherein the metal layer comprises an effective antimicrobial amount of silver microparticles so that the display exerts an antimicrobial effect, wherein the polygon has at least one interior angle that is an acute angle and wherein at least part of pairs of adjacent periodic elements among the plurality of periodic elements is arranged such that vertices of acute angles in a pair of adjacent periodic elements point at each other.
