ABSTRACT:
In a three-dimensional video display apparatus, accommodation and convergence among physiological characteristics of eyes are abandoned, thereby resulting in generation of unnatural three-dimensional video. For example, even when eyes are moved, a screen is not changed, and a cardboard effect and/or a miniature garden effect may be caused, so that the eyes may be greatly fatigued. Light emission sources1R,1G, and1I, holograms3R,3G, and3I, and a transparent display component4are provided, and a plurality of reflectors6are formed in the display component4so as to be positioned at intersections in a space lattice. Lights2R,2G, and2I emitted from the light emission sources1R,1G, and1I are incident on the holograms3R,3G, and3I, respectively, and a plurality of diffracted converging lights5G,5B, and5I are generated through the holograms3R,3G, and3I, respectively, and each focused on light focusing points near the plurality of reflectors6, and the diffracted converging lights5G,5B, and5I are each reflected by the plurality of reflectors6, and emitted to the outside through an emission surface7sof the display component4.
