PROBLEM TO BE SOLVED: To allow authenticity determination against forgery, imitation, and the like with relatively easy work, and to improve security and innovating design.SOLUTION: A display body has a polyhedral shape having a plurality of faces, and each face of the polyhedral shape is constituted of a unit pixel group comprising a plurality of consecutive unit pixels 3, and the plurality of unit pixels in the unit pixel group are constituted of minute irregularities 5 having slopes 4 directed at least in the same direction. Directions of the slopes 4 of minute irregularities 5 are defined correspondingly to respective faces of the polyhedral shape, and light beams different in brightness are emitted from respective faces of the polyhedral shape when light impinges from a certain direction. |
