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 sources 1R, 1G, and 1I, holograms 3R, 3G, and 3I, and a transparent display component 4 are provided, and a plurality of reflectors 6 are formed in the display component 4 so as to be positioned at intersections in a space lattice. Lights 2R, 2G, and 2I emitted from the light emission sources 1R, 1G, and 1I are incident on the holograms 3R, 3G, and 3I, respectively, and a plurality of diffracted converging lights 5G, 5B, and 5I are generated through the holograms 3R, 3G, and 3I, respectively, and each focused on light focusing points near the plurality of reflectors 6, and the diffracted converging lights 5G, 5B, and 5I are each reflected by the plurality of reflectors 6, and emitted to the outside through an emission surface 7s of the display component 4.
