    Abstract: There is provided a display that displays a diffraction image from which an observer can easily perceive a stereoscopic effect. A display (1) includes a relief structure forming layer having a major surface which is provided with a relief type diffractive structure that displays an image of 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. The above region includes first and second regions (R1, R2). A portion of the diffractive structure in the first region (R1) 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 the second region (R2) 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 continuously changing image can be displayed in a wide angular range without causing a feeling of unease to observers. A display includes a plurality of pixels (PX) each including a plurality of first subpixels (SPX1) and a plurality of second subpixels (SPX2). In each of the plurality of pixels (PX) of the display, when illumination light is applied to the plurality of first subpixels (SPX1) from a normal direction, no diffracted light emerges from the plurality of first subpixels (SPX1), or first diffracted light emerges from the plurality of first subpixels (SPX1) in a first angular range, and when the illumination light is applied to the plurality of second subpixels (SPX2) from the normal direction, no diffracted light emerges from the plurality of second subpixels (SPX2), or second diffracted light having a wavelength equal to that of the first diffracted light emerges from the plurality of second subpixels (SPX2) in a second angular range wider than the first angular range, at an intensity lower than that of the first diffracted light; and the plurality of pixels (PX) are configured to display a continuously changing image using the first diffracted light and the second diffracted light.

    Abstract: The present invention aims to provide a display that exhibits better anti-counterfeiting effects and an article with the display. The display of the present invention 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 of the uneven-structure-forming layer. 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.
