发明名称 DISPLAY BODY USING DIFFRACTION GRATING
摘要 <p>PROBLEM TO BE SOLVED: To provide a display body, which uses a diffraction grating, excellent in visibility and having a high preventing effect against forgery by constituting the display pattern from an assembly in which diffraction gratings are arranged at random. SOLUTION: In the display body, which uses a diffraction grating having a display pattern 31 constituted from diffraction gratings, the domain of the display pattern 31 is divided into a plurality of pixels 311, 312, 313, 314 and 315. The display pattern 31 is constituted by assigning, at random, a plurality of kinds of diffraction gratings different in at least one of the line width, pitch and angle of gratings to the plurality of pixels 311, 312, 313, 314 and 315.</p>
