DISPLAY BODY, DEVICE PROVIDED WITH DISPLAY BODY, AND DISPLAY BODY MANUFACTURING METHOD

There are provided a display having antimicrobial properties, a device with a display, and a method of producing a display. In the display, images with different appearances can be observed depending on the observation conditions, and wavelength selectivity can be enhanced in a reflected or transmitted light image. The display is provided with a periodic structure that is dielectric and includes a support and a plurality of periodic elements. The support has 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 are either convexities projected from the reference plane or concavities recessed in the reference plane. The display is also provided with a metal layer disposed on a surface of the periodic structure. The surface corresponds to a plane including a region of the reference plane surrounding the individual periodic elements and surfaces of the periodic elements. The metal layer has a profile conforming to a surface profile of the periodic structure. The plurality of periodic elements have an interval therebetween in a first direction in which the plurality of periodic elements are arranged in a two-dimensional lattice form. The interval is different from an interval between the periodic elements in a second direction intersecting the first direction.
