A naked-eye 3D display device and a method for realizing naked-eye 3D display. The device comprises: light sources (401, 501-503, 601), wherein the light sources (401, 501-503, 601) are located below a view window generation device; and the view window generation device, comprising: a phase information modulation device (410) for phase modulation, and a view angle image information modulation device (420) for amplitude modulation, wherein pixels (421-424, 521-523) of a view angle image generated by the view angle image information modulation device (420) match and are aligned with viewpoint pixels (411-414, 511-513) generated by the phase information modulation device (410). By using a holographic imaging and wave-front conversion principle, the phase information modulation device (410) is skilfully used for phase modulation, and at the same time, the view angle image information modulation device (420) is used for amplitude modulation, wherein the pixels (421-424, 521-523) of the view angle image generated by the view angle image information modulation device (420) match and are aligned with the viewpoint pixels (411-414, 511-513) generated by the phase information modulation device (410). Namely, an assembly with a phase modulation function is combined with the display technology with an amplitude modulation function, so that naked-eye 3D display is realized, and 3D image information is presented.
