摘要： 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.
