Abstract: A higher forgery prevention effect is realized. A display comprises a first interface section provided with a relief-type diffraction grating constituted by a plurality of grooves, and a second interface section provided with a plurality of recesses or projections arranged two-dimensionally at a center-to-center distance smaller than the minimum center-to-center distance of the plural grooves and each having a forward tapered shape, wherein the first interface section is formed by arranging a plurality of first pixels, the plural first pixels including two or more pixels different from each other in at least one of spatial frequency, azimuth angle, and depth of the plural grooves, and ratio of an area of the diffraction grating to that of the first pixels, and the second interface section is formed by arranging a plurality of second pixels, the plural second pixels including two or more pixels different from each other in at least one of shapes, depth or height, center-to-center distance, and arrangement pattern of the plural recesses or projections.
