<p><P>PROBLEM TO BE SOLVED: To implement a high forgery prevention effect. <P>SOLUTION: A display body is provided with a plurality of pixels. Each of the plurality of pixels includes a first sub-pixel, and at least one of the plurality of pixels includes the first sub-pixel including a first region which comprises a plurality of concave or convex portions each having a forward tapered shape, which are two-dimensionally arranged with center-to-center distances in a range of 250 to 500 nm, and a second region which comprises a plurality of concave or convex portions each having a forward tapered shape, which are provided with center-to-center distances of 500 nm or less so as to be shifted from an azimuth angle of two-dimensional arrangement of the first region by an angle equal to or larger than 5°and equal to or smaller than 40°, and each of the other plurality of pixels includes the first sub-pixel including at least one of the first and second regions. The display body displays a first image based on a distribution of the first regions in a second condition that the display body is observed in an oblique direction crossing a normal of a principal surface of the display body. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
