A three-dimensional spatial image display apparatus includes a three-dimensional image display including a two-dimensional image display and a beam controlling element, a retro-reflective screen, and an optical element. As a gazing point on the beam controller element of the 3-dimensional image display, the 3-dimensional spatial image is generated by displaying a parallax image acquired from a plurality of directions so that an observer can look only from the direction which corresponds to the acquisition direction.
