Abstract: A display body includes a display surface including a plurality of display region groups. Each display region includes at least one reflection surface that is configured to reflect light incident on the display surface toward an area including a corresponding one of reflection directions that are associated with the respective display region groups. Each display region group is configured to form an image unique to the display region group in a corresponding one of the reflection directions through reflection of light on the reflection surfaces in the display region group. The display region groups are configured to form, in two adjacent ones of the reflection directions, different images that have a interrelation between each other.
