Abstract: An optical structure in which a plurality of cells having a pleat structure are regularly aligned in contact with each other on an embossed surface, the pleat structure has a plurality of inclined surfaces parallel to each other, the pleat structure has a linear ridge line formed of an inclined surface end, each ridge line is parallel to a straight line approximating a smooth curved line, depths of pleat structures of adjacent cells are uniform, an interval of ridge lines in a cell continuously varies between adjacent cells, an inclined surface group of each aligned cell displays a smooth curved surface appearance by reflected light of the inclined surfaces, and a distance of a ridge line, among ridge lines in each cell, closest to a predetermined reference point in the cell from the predetermined reference point has artificial fluctuation.

Abstract: Characteristic visual effects can be achieved. A display (1) includes one or more relief structures (RS1). Each relief structure (RS1) includes a smooth first reflection surface (21) and a plurality of protrusions or recesses. Each top surface of the protrusions or each bottom of the recesses is a smooth second reflection surface parallel to the first reflection surface. Each relief structure (RS1) displays a mixed color as a structural color.
