Zusammenfassung:	An optical structure surface including a plurality of display region groups including a first display region group and a second display region group. In each display region group, an azimuth angle is formed between a projection direction and a reference direction, and a plurality of reflective surfaces belonging to the display region produce an image. A plurality of display regions include a set of display regions whose azimuth angles are different from each other, and the plurality of display regions display an image unique to the display region group in a display direction by a plurality of reflective surfaces of each of the display regions. The display directions of the first display region group and the second display group are different to provide a different brightness to their respective images, in the respective display directions of the images.
