Abstract
A technique that is suitable for use in a vehicle and capable of displaying an air floating video with high visibility is provided. The present invention contributes to 'Goal 3: Ensure healthy lives and promote well-being for all at all ages' and “Goal 9: Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation” in the sustainable development goals. The air floating video display apparatus includes a housingwhich is attachable at a position near a ceiling or a rearview mirror in the vehicle and stores a video display apparatus. A polarization separation memberand a retroreflectoron which a λ/4 plateis provided, which are each arranged at a predetermined angle, are provided outside the housing. A video light of a specific polarized wave from the video display apparatusis reflected by the polarization separation member, is retroreflected by the retroreflector, and passes through the λ/4 plateto be subjected to polarization conversion, and the video light after the polarization conversion passes through the polarization separation memberto display an air floating videoat a predetermined position.
