PROBLEM TO BE SOLVED: To provide a spatial video display device capable of forming an image in a space, while the three-dimensional shape of an object is maintained. SOLUTION: Incident light from the object is reflected twice by the first and the second light reflection surfaces of a first reflection type plane-symmetric imaging element, to form the first real image of the object plane-symmetrically with respect to the object about the first reflection type plane-symmetric imaging element and incident light from the first real image is reflected twice by the first and the second light reflection surfaces of a second reflection type plane-symmetric imaging element, to form the second real image of the object plane-symmetrically with respect to the first real image about the second reflection type plane-symmetric imaging element.
