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.
