A display is provided with a periodic structure that is dielectric and includes a support and a plurality of periodic elements. A plurality of periodic elements is arranged on a reference plane in a two-dimensional lattice form having a sub-wavelength period and are either convexities projected or concavities recessed in the reference plane. A metal layer is 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's profile conforms 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.

A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.
