PROBLEM TO BE SOLVED: To provide a three-dimensional aerial video display with a volume scanning method applying various real mirror video imaging optical systems, in particular, a distortion-free three-dimensional aerial video display. SOLUTION: The volume scanning type three-dimensional aerial video display device X1 includes: a real mirror video imaging optical system 2 which can form the real image of an object to be projected in a plane-symmetric position with respect to a geometric plane S1 being a symmetric surface thereof; a display 3 which is arranged on an undersurface side of the symmetric surface S1 and has a display surface 31 for displaying the video O as the object to be projected; and a drive means 4 for operating the display 3 so as to perform motion including a component in a perpendicular direction with respect to the display surface 31. The display device is adapted to change the video O displayed on the display surface 31 in synchronization with the operation of the display 3 by the drive means 4, thereby forming the video O as the three-dimensional aerial video P in the space on the top surface side of the symmetric surface S1.
