PROBLEM TO BE SOLVED: To provide a display body capable of achieving higher forgery prevention effect than heretofore, and to provide an article with display body on which the display body is stuck as a label. SOLUTION: The display body is composed of a relief structure formation layer having irregularities on one of the principal surfaces. The one principal surface is divided into a plurality of kinds of areas, some areas of which (a first interface part) are areas not generating diffracted light in the normal direction, and some other areas of which (a second interface part) are areas scattering visible light. In the first interface part, a plurality of projections or recesses are arranged so that distances between their centers are shorter than the shortest wavelength of visible light. In the second interface part, a plurality of projections or recesses linearly arrayed in almost uniform direction are arranged. Thus, when viewed from the normal direction of the principal surface, brightness is different between the first interface part of low reflection and low scattering and the second interface part of high scattering, and a visible image can be viewed. When viewed from an oblique direction, another image can be viewed. COPYRIGHT: (C)2010,JPO&INPIT |
