Abstract

A compact and portable air floating video display apparatus includes a housing that can be installed in a bottle holder in a vehicle. A video display apparatus, a beam splitter, a retroreflector, a retardation plate, and a plane mirror are provided in the housing. In the air floating video display apparatus, a video light of a specific polarized wave from the video display apparatus is reflected by the plane mirror, transmitted through the beam splitter, and subjected to polarization conversion by being reflected by the retroreflector and passing through the retardation plate. Then, the video light is reflected by the beam splitter and transmitted through the window, thereby displaying an air floating video outside the apparatus.
