Abstract
The present disclosure enables a space floating video having few ghosts to be obtained, and a space floating video apparatus suitable for inputting without causing fewer erroneous operations. The space floating video display apparatus includes: a display panel for displaying a video; a light source apparatus that supplies light of a specific polarization direction to the display panel; a retroreflection plate for reflecting video light from the display panel and displaying a space floating video of real image in air by means of the reflected light; and a light-shielding member that, among a plurality of space floating videos which are formed by the video light from the display panel, blocks a portion of the video light that is likely to form a space floating video other than desired space floating videos.
