Claim Text:
1. A display comprising: a substrate with a light-transmitting property, said substrate having a first surface and a second surface opposite to each other; a relief structure-forming layer having a first surface and a second surface opposite to each other and disposed relative to the substrate such that the first surface of the relief structure-forming layer faces the first surface of the substrate, the second surface of the relief structure-forming layer including a relief-structured region, the relief-structured region including recessed or protruding portions arranged with constant periodicity in first and second directions crossing each other; a light-reflecting layer disposed at least partially on the second surface of the relief structure-forming layer and at least partially covering the relief-structured region; and a printed layer disposed at one of first to third positions, the first position being at a side of the substrate opposite the relief structure-forming layer, the second position being between the relief structure-forming layer and the light reflecting layer, and the third position being at a side of the light-reflecting layer opposite the relief structure-forming layer, wherein a center-to-center distance of the recessed or protruding portions and a height or depth of the recessed or protruding portions are configured such that the display displays black or dark gray at a position corresponding to a portion of the relief-structured region covered with the light-reflecting layer when the display is observed perpendicularly while irradiating the display with light in a direction perpendicular to the first surface of the substrate and such that the display displays colors of diffracted light when irradiated with light at an acute angle, wherein center-to-center distances of the recessed or protruding portions is 400 nm or less, wherein the height or depth of the recessed or protruding portions is 200 nm or more and 600 nm or less, and wherein at least a part of the printed layer is formed from a functional ink that changes color according to an observation angle.
