Abstract: A display body includes a first display part, which displays first information, and a second display part, which displays second information of a larger display size than the first information. The second display part includes the entire first display part as a part of the second display part. The first display part has a plasmon structure. The plasmon structure includes an interface between a metal layer and a dielectric layer, which transmits light, and is configured so that surface plasmons are excited in the interface to change irradiation light with which the interface is irradiated to transmitted light having a color different from that of the irradiation light. The first information is displayed with the transmitted light.

Abstract: In display, in a plan view facing an obverse surface of a reflection layer, first reflection surfaces are substantially square in shape, and a second reflection surface occupies gaps between adjacent ones of the first reflection surfaces. The distance between the first reflection surfaces and the second reflection surface in the thickness direction of a substrate has an extent that the obverse surface of the reflection layer emit colored light by interference between light reflected from the first reflection surfaces and light reflected from the second reflection surface. In a plan view facing the obverse surface of the reflection layer, more than one of the first reflection surfaces are located on each of a plurality of imaginary lines. On a straight line intersecting more than one of the imaginary lines, distances between adjacent ones of the imaginary lines have different extents.

Abstract: A display includes a substrate with a light-transmitting property, a relief structure-forming layer disposed on at least one surface of the substrate and including a relief-structured region on a surface thereof opposite to its surface in contact with the substrate, a light-reflecting layer disposed on the surface of the relief structure-forming layer including the relief-structured region, and a printed layer formed on a surface of the substrate opposite to the surface on which the relief structure-forming layer is disposed, or between the relief structure-forming layer and the light-reflecting layer, or on a side of the light-reflecting layer opposite to its surface in contact with the relief structure-forming layer. The relief-structured region is constituted by recessed or protruding portions arranged two-dimensionally, has low reflectivity and low diffusibility under a normal illumination condition, and exhibits a diffracted light-emitting property under a specific condition.
