Air floating video display apparatus

An air floating video display apparatus configured to display an air floating video, the air floating video display apparatus comprising:

• a video display apparatus;
• a polarization separator configured to reflect a video light of a specific polarized wave from the video display apparatus and transmit a video light of the other polarized wave;
• a retroreflection module configured to retroreflect the reflected video light of the specific polarized wave from the polarization separator and convert it into a video light of the other polarized wave and including a λ/4 plate and a retroreflector;
• and
• a housing configured to hold the video display apparatus, the polarization separator, and the retroreflection module,
• wherein the video light of the other polarized wave from the retroreflection module is transmitted through the polarization separator to form the air floating video which is a real image at a predetermined position outside the housing, and
• wherein, in a relationship between a first angle that the video display apparatus forms with respect to the polarization separator and a second angle that the retroreflection module forms with respect to the polarization separator, the second angle is different from the first angle.
