Abstract:
1. An image display sheet, which is constituted by laminating a lenticular sheet composed of arrangement of a plurality of cylindrical lenses and an image forming layer, and in which an image formed on the image forming layer from a convex shape side of the cylindrical lenses of the lenticular sheet is formed to be observable as virtual image provided with movement, or movement and deformation, wherein: a plurality of images for observing virtual images for displaying the virtual image in association with the cylindrical lenses are formed repeatedly on the image forming layer so as to correspond to the cylindrical lenses respectively one-on-one, the size of the image for observing the virtual image in the arrangement direction of the cylindrical lens and the image for observing the virtual image is the size obtained by reducing the size of the virtual image along the arrangement direction, the size of the image for observing the virtual image in the vertical direction to the arrangement direction is the same size as the virtual image in the vertical direction to the arrangement direction, and a difference between an arrangement pitch length of the cylindrical lenses and a pitch length of the image for observing virtual image formed repeatedly on the image forming layer is in a range of not more than 10% with respect to the arrangement pitch length of the cylindrical lenses or the pitch length of the image for observing virtual image.
