Zusammenfassung:	A more favorable air floating video display apparatus is provided. This technique contributes to the Sustainable Development Goals that are "the third goal: Good Health and Well-being (for all people)", "the ninth goal: Industry, Innovation and Infrastructure" and "the eleventh goal: Sustainable Cities and Communities". The air floating video display apparatus includes: a video display; and a retro-transmitting plate transmitting video light emitted from the video display to form an air floating video, a light path length of video light having been emitted from a display surface of the video display through the retro-transmitting plate to a position of the air floating video changes depending on a position on the display surface of the video display from which the video light is emitted, and the video display is configured to change a light emission amount per unit area to depend on the light path length.
