Abstract: The distance between the first reflection surfaces and the third reflection surface in the thickness direction of a substrate is a distance that is able the obverse surface of the reflection layer to emit light of a first color by interference between light reflected from the first reflection surfaces and light reflected from the third reflection surface. The distance between the second reflection surfaces and the third reflection surface in the thickness direction of the substrate is a distance that is able the obverse surface to emit light of a second color by interference between light reflected from the second reflection surfaces and light reflected from the third reflection surface. The obverse surface emits light of a third color that includes the light of the first color and the light of the second color.

Abstract: Each protrusion surface has a shape of a strip extending in an extension direction perpendicular to the arrangement direction. Each protrusion surface tapers toward a top section in a thickness direction of an uneven structure. Each depression surface has a shape of a strip extending in the extension direction. Each depression surface tapers toward a bottom section in the thickness direction of the uneven structure. The protrusion surfaces and the depression surfaces are arranged at a period that limits reflection of light that is incident on the uneven surface in a front-view direction of the uneven surface and diffracts the light incident on the uneven surface to emit diffracted light in an oblique view direction of the uneven surface. The uneven structure has a property of absorbing light incident on the uneven structure.

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.
