A two-dimensional image is displayed on a flat display device. A solid diffusion panel which is composed of six transparent panels is disposed in an optical path of image light emitted from the flat display device and is moved periodically in a depth direction. Sectional images of a 3D solid image are drawn on reflection surfaces of the six transparent panels by means of image light emitted from the flat display device. Because of the afterimage effect, a viewer can recognize, as a 3D solid image, reflection light coming from the solid diffusion panel.
