Abstract: A display comprising a microlens array which includes microlenses sufficiently smaller than the length of one side of an effective region and in which the optical axes of two adjacent microlenses are independent of each other, and a two-dimensional display image or an image support for supporting such a two-dimensional display image so that the two-dimensional display image is opposed to the microlenses and disposed at a point close to the focal points of the microlenses and at a point not close to the curved surfaces of the microlenses in a position between the focal points of the microlenses and the curved surfaces of the microlenses and not very close to the focal points and the curved surfaces of the microlenses, wherein the observer facing the microlenses can view the two-dimensional display image through the microlenses. The two-dimensional display image can be viewed like a three-dimensional image only by varying the position of the image without varying the size of the image equivalently.
