PROBLEM TO BE SOLVED: To provide a device changing a stereoscopic image by arranging respective pixels so as to share respective stereoscopic angle central points and constituting so that pixel units of a structure that plural pieces of light emission surfaces having directivity at every stereoscopic angle are arranged on a display surface are arranged in the crisscrossed directions. SOLUTION: Light outgoing from a light emitting diode 1 is directed so as to expand only in the direction of the stereoscopic angle αby a lens 2. The pixel unit 3 is one that the pixels emitting the light only in such a specified stereoscopic angle direction are integrated so that respective stereoscopic angle centers become the same point P, and a stereoscopic display screen 5 is constituted by regularly and crisscross arranging plural pieces of such a pixel units 3. This screen 5 is positioned as a plane in space to be displayed, and plural pixels on respective pixel units 3 are controlled so as to reflect intensity of a light component of space passing through the centers of respective stereoscopic angles α. Thus, an observed picture is changed by that an observer moves one's viewpoint. |
