    Abstract: A display medium that is able to arbitrarily change the display of recorded optical image information even when viewed from the same field of view, and an image display method that uses that display medium. The display medium includes a diffraction structure section on which optical image information is recorded, a chromic device that controls the reflection and transmission using voltage, and a power supply that is connected to the chromic device.

    Abstract: An information recording medium is formed by laminating a transparent protective layer and a base material having laser color-developing properties. The information recording medium includes an intermediate layer that is disposed between the transparent protective layer and the base material. In the information recording medium, the intermediate layer includes a diffraction structure layer that has a diffraction structure, and a first reflective layer that reflects visible light and is destroyed when irradiated with a laser beam. Light, when incident from a transparent protective layer side, causes a diffracted light pattern to appear in the diffraction structure layer so as to be observable from the transparent protective layer side. A laser beam, when applied from the transparent protective layer side, passes through the diffraction structure layer, destroys the first reflective layer, and develops color in the base material.

    Abstract: Provided are diffraction structure transfer foil that further improves usefulness of the diffraction structure transfer foil in authenticity determination by allowing a greater variety of diffracted-light patterns to be observed, and a forgery prevention medium using the diffraction structure transfer foil. The diffraction structure transfer foil (21) includes a transfer foil substrate (1), a peeling-off protective layer (2) that is laminated on one surface of the transfer foil substrate (1), a laminated body for diffracted-light delivery (13a) that is laminated on the peeling-off protective layer (2), and an adhesive layer (9) that is laminated on the laminated body for diffracted-light delivery (13a). The laminated body for diffracted-light delivery (13a) includes a diffraction structure forming body in which a plurality of diffraction structures (4 and 7) are formed, and a reflective layer (5a or 8a) that is formed in accordance with each of the plurality of diffraction structures (4 and 7). A transmission density of one reflective layer (5a) of the plurality of reflective layers (5a and 8a) is in a range of 0.01 to 0.9, and a transmission density of the other reflective layer (8a) is 1.0 or greater.
