PROBLEM TO BE SOLVED: To enable a user to enjoy changes of colors by angles at which images are visible. SOLUTION: This display device consists of a display part H and a light source l which illuminates its back. The display part is composed of image forming sheets 6 and 7, two polarizing plates 5a and 5b which hold these sheets and a milky white plastic sheet 4 superposed on the polarizing plate 5a on the light source side. A first sheet mold 6 is a transparent plastic film like polypropylene and is a sheet which develops bright colors by the prism effect of the polarizing plates 5a and 5b. A second sheet mold 7 is a silhouette of a dance formed by blanking black paper. Since the sheet mold is hemmed with the black paper, the plastic film portions are delicately changed by the refraction of light and expression in different colors is made possible.
