Abstract: A display including a plurality of pixels each including a plurality of first subpixels and a plurality of second subpixels. In pixel, when illumination light is applied to the first subpixels from a normal direction, no diffracted light emerges from the plurality of first subpixels, or first diffracted light emerges from the plurality of first subpixels in a first angular range. When illumination light is applied to the second subpixels from the normal direction, no diffracted light emerges from the plurality of second subpixels, or second diffracted light having a wavelength equal to that of the first diffracted light emerges from the plurality of second subpixels in a second angular range wider than the first angular range, at an intensity lower than that of the first diffracted light; with the pixels configured to display a continuously changing image using the first diffracted light and the second diffracted light.

Abstract: A display including a relief structure forming layer having a major surface with a relief type diffractive structure that displays a three-dimensional object as a diffraction image; and a reflective layer at least partially covering a region of the major surface where the diffractive structure is provided. A portion of the diffractive structure in a first region includes first and second linear parts forming a first lattice, and first parts arranged in respective gaps of the first lattice. The first and second linear parts each having a solid line shape form a first pattern. A portion of the diffractive structure in a second region includes third and fourth linear parts alternately arranged in the width direction thereof. The third linear parts each having a dashed line shape and the fourth linear parts each having a dashed or dotted line shape form a second pattern.

Abstract: A personal identification medium is provided that includes a decorative layer provided with an antenna, and a laser marking layer in which a personal information marking portion is marked on the decorative layer, where the antenna includes a non-decorative portion and a decorative portion connected to the non-decorative portion, and the personal information marking portion formed on the laser marking layer overlaps at least a portion of the decorative portion formed on the decorative layer.

Abstract: A display that exhibits improved anti-counterfeiting effects. The display includes an uneven-structure-forming layer having an uneven structure on one surface and a reflecting layer that covers at least part of an unevenly structured surface. In the display, the uneven-structure-forming layer includes a first region group including a plurality of first regions, each first region including a flat part and a plurality of convexities or a plurality of concavities, the top surface of each of the convexities or the bottom surface of each of the concavities is substantially parallel to a surface of the flat part; distances between the centers of adjacent convexities or concavities are not equal; the convexities have a uniform height, or the concavities have a uniform depth; the first region group is formed, with the first regions arrayed inside at a regular pitch.
