摘要: 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.

摘要: 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.
