Abstract:
A virtual image display apparatus configured to be in front of at least one eye of a user includes an image display unit, a first beam splitting unit, and a reflection-refraction unit. The image display unit provides an image beam. The first beam splitting unit disposed on transmission paths of the image beam and an object beam causes at least one portion of the object beam to propagate to the eye and causes at least one portion of the image beam to propagate to the reflection-refraction unit. The reflection-refraction unit includes a lens portion and a reflecting portion on a first curved surface of the lens portion. At least part of the image beam travels through the lens portion, is reflected by the reflecting portion, travels trough the lens portion again, and is propagated to the eye by the first beam splitting unit in sequence.
