Abstract: A display includes first and second portions and is deformable between a first state in which the portions are spaced apart from each other and a second state in which the portions overlap each other, wherein the first portion includes first and second regions each having a shape extending in a first direction and alternately and regularly arranged in a second direction, each of the first regions being a light-permeable region provided with a light-deflecting structure, and each of the second regions being a transparent region having flat front and back surfaces, and a latent image is recorded in the second portion, the latent image being identifiable or easy to identify when observed through the first portion in the second state.

Abstract: A display technique capable of displaying special images. A display includes a light shielding layer having a plurality of slits arranged at intervals in a width direction thereof, and an image recording layer that faces a first major surface of the light shielding layer at an interval and in which a latent image is recorded, the latent image being rendered visible by being partially concealed by the light shielding layer.

Abstract: A display technique capable of displaying special images. A display includes an image display layer and a mask layer. The image display layer includes one or more colored portions, and displays a transmitted light image corresponding to the one or more colored portions when illuminated with white light. The mask layer includes a transparent material layer having a first major surface and a second major surface, and the first major surface includes one or more regions each composed of first and second strip-shaped parts alternately arranged in a width direction. The second strip-shaped parts are provided with a relief structure. A portion of the mask layer corresponding to at least one of the one or more regions conceals a portion of the transmitted light image corresponding to the second strip-shaped parts.
