PROBLEM TO BE SOLVED: To provide a novel display body 1 having a high forgery prevention effect, capable of determining authenticity without using any special device, and having high designability, an article 25 with the display body, and an authenticity determination method for the display body 1 and the article 25 with the display body.SOLUTION: The display body 1 including a high polymer film laminate in which two types of high polymer films 6 of a first phase 7 and a second phase 9 different from each other in physical property are alternately stacked on a substrate 11 is characterized in that at least one of the high polymer films 6 has the nature of swelling by liquid absorption and contracting by drying, a micro uneven structure 2 exhibiting the optical effect of at least one of diffraction, interference, and scattering is formed on the surface of the high polymer film laminate, and the substrate 11 is stretchable.SELECTED DRAWING: Figure 1 |
