摘要： 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.

摘要： A display body includes a first surface, a second surface, a first optical component, and a second optical component. The first surface includes a first optical surface and a second optical surface. First light is incident on the first surface from an observation side. The second surface is located opposite to the observation side with respect to the first surface. Second light is incident on the second surface from a side opposite to the observation side with respect to the second surface. The first optical component includes the first optical surface and forms first information, which is displayed on the observation side, from the first light received on the first optical surface. The second optical component includes the second optical surface. The second optical component receives the second light transmitted through the second surface, forms second information, which is displayed on the observation side, from the second light, and emits the second information from the second optical surface.

摘要： An integrated three-dimensional display (10) includes a recording surface (14) which includes a calculated element region (16) in which phase components of light from light converging points (Sn) of a holographic reconstructed image (40) are calculated, and a phase angle recorded area (18) for recording a phase angle calculated based on the phase components. The phase angle recorded area (18) includes a plurality of monochromatic regions (22) having a uneven structure surface. The phase angle is recorded in an overlap area (19) in which the calculated element region (16) and the phase angle recorded area (18) overlap each other. Light converges on the light converging points (Sn) at specific distances (Zn) from the recording surface (14), the specific distances being determined for the respective light converging points (Sn) even when light reflected from the plurality of monochromatic regions (22) converges.
