Abstract: A three-dimensional display including a laminate sheet with first element cells with recorded personal identification information, and second element cells carrying an authentication medium with visible personal identification information, including a first region and a second region formed by arranging first element cells and second element cells which form respective phase shift structures; the first element cells and the second element cells arranged in an interleaved manner at a predetermined ratio to form respective three-dimensional structures; the first region and the second region are visible respectively from first and second sides of the laminate sheet; a first reconstructed image is produced on the first side of the laminate sheet due to the phase shift structure formed by the first element cells; and a second reconstructed image is produced on the second side of the laminate sheet due to the phase shift structure formed by the second element cells.

Abstract: A display body includes a base material having a first region, a second region, and a third region. In the display body, the first region is formed with a code or an image of identification information, and the second region is formed with a hidden code containing information obtained by encoding at least a part of the identification information. An encrypted ciphertext is recorded in the third region, and the ciphertext is generated from at least one of the code of the identification information and the hidden code.

Abstract: An optical assembly includes a spacer layer which is translucent or transparent; an image forming reflector which has a reflective layer being formed at least in a first region of the spacer layer; and a protective layer which is laminated over the spacer layer and the image forming reflector and the protective layer being translucent or transparent. The spacer layer is made of a polyolefin or/and a polymer containing an aryl group. The image forming reflector includes a visible image which is authenticatable. The image forming reflector has an individual information record in which a code is stored in the form of a plurality of removed linear segments. The image forming reflector has white level regions and a black level region in planar view. Each of the white level regions has the removed linear segments formed therein. The black level region is interposed between the white level regions.
