COLOR DISPLAY BODY, AUTHENTICATION MEDIUM AND AUTHENTICITY DETERMINATION METHOD OF COLOR DISPLAY BODY

A forming mold has a surface in contact with a deposited film, a part or an entire part of the surface being a first wavy surface. A wave period of the first wavy surface is in a range of 250 nm or more and 500 nm or less. The deposited film conforms to the surface of the forming mold. The first wavy surface includes a plurality of rib surfaces, a plurality of groove surfaces, and a plurality of taper surfaces connecting the rib surfaces to the respective groove surfaces. The deposited film has a peak zone, a valley zone, and a transition zone. One of the peak zone, the valley zone, and the transition zone and another one of the peak zone, the valley zone, and the transition zone are different from each other in at least one of thickness and volume density, or one of the peak zone, the valley zone, and the transition zone has portions different from each other in at least one of thickness and volume density.
