PROBLEM TO BE SOLVED: To provide a stereoscopic display device which projects a video in a space without using smoke and mist, and completely without a support.SOLUTION: A point light source 10 such as an LED light source is arranged in front of a screen 11 consisting of a retroreflective material sheet, and a direction of the screen 11 is observed from backward of the point light source 10. When an observer watches the point light source 10, a mass 13 of light dimly floats in the surroundings of the point light source 10. The mass 13 of light is visually recognized so as not to exist in a direction of the screen 11 but to exist in the surroundings of the point light source 10. Even when the observer 12 horizontally moves, and a position to the screen 11 and the point light source 10 is changed, the mass 13 of light stays in the surroundings of the point light source 10. Various molding can be realized in a space by arranging a plurality of such point light sources 10 like graphics, characters, and solids. |
