Patent abstract
A spatial image display apparatus includes a display element including a plurality of pixels which are two-dimensionally arranged, and an imaging device that has a substrate including a plurality of dihedral corner reflectors arranged, the display element is disposed in a first space on one main surface of the substrate, and the imaging device forms a real image of a display image by the display element, in a second space on the other main surface of the substrate. The plurality of pixels are arranged in a period corresponding to a frequency that is equal to or less than a minimum spatial frequency at which an MTF value relative to a spatial frequency of the imaging device is minimized.
