PROBLEM TO BE SOLVED: To provide a stereoscopic image expressing structure in which the shape of a stereoscopically viewed image is changed along with a change in observation angles; and a shape change printed matter using the structure.SOLUTION: A stereoscopic image expressing structure includes: shape change streak groups in which an original image is divided into a plurality of regions, streak groups having equal streak widths are arrayed in each of the regions, and each of the regions are arranged so that the streak widths become smaller sequentially toward the same direction; and filter streak groups in which transparent or translucent filter streaks are arranged in a parallel line form. When the shape change streak groups and the filter streak groups are overlaid and observation angles are continuously changed, the shape of the image is changed and can be visually recognized.SELECTED DRAWING: Figure 8 |
