PROBLEM TO BE SOLVED: To provide a display device capable of presenting a stereographic two-dimensional image rich in depth floating in a space at a distance from a device body.SOLUTION: A display device includes; a mounting table 1 having a mounting surface 1a; a light source 3 for irradiating a sheet P on the mounting surface 1a with light; a panel-like imaging optical element (micro-mirror array 2); and a case 10 having a predetermined surface (top surface) fitted with the imaging optical element 2. The mounting surface 1a holds the sheet P at a predetermined tilt angle α with respect to an element surface H of the imaging optical element 2. The light projected from the light source 3 is reflected by a surface of the sheet P, transmits through the imaging optical element 2, and forms a projection image (I') of an image I on the sheet P, which floats above an outer surface (top surface 2a) of the panel-like imaging optical element 2. |
