An object is to provide an image display sheet provided for position detection of an object to be observed so as to realize a smooth pseudo moving image. The image display sheet is provided for an object 3000 to be observed for position detection and constituted by laminating a lenticular sheet composed of arrangement of a plurality of cylindrical lenses and an image forming layer, and 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. A plurality of images for observing virtual images for displaying virtual images 104A, 104B 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, an arrangement pitch length in a horizontal direction of the flat convex lenses and a pitch length in a horizontal direction of the image for observing virtual image differs in a range of not more than 10%, and an arrangement pitch length in a vertical direction of the flat convex lenses and a pitch length in a vertical direction of the image for observing virtual image differs in a range of not more than 10%, and the virtual image smoothly moving with respect to displacement of an angle θ at which the object 3000 is visually observed is thereby observed.
