Abstract: A virtual image display apparatus configured to be disposed in front of an eye of a user is provided. The virtual image display apparatus includes an image displaying unit providing an image beam, a first beam splitting unit disposed on the transmission path of the image beam, and an image correction unit disposed on the transmission path of the image beam from the first beam splitting unit. The image correction unit includes a first optical element, a second optical element, and a planar reflective element. The image beam emitted by the image displaying unit sequentially travels through the first beam splitting unit, the first optical element, and the second optical element, and is reflected by the planar reflective element, then travels through the second optical element and the first optical element again, and is transmitted to the eye by the first beam splitting unit.

Abstract: An optical lens, adapted for transmitting an image light beam generated by an image display unit to at least one eye of a user. The optical lens includes a reflecting unit, an L-type lens and a diffractive optical element. The reflecting unit, the L-type lens and the diffractive optical element are disposed on a transmission path of the image light beam. The L-type lens has a first portion and a second lens portion integrally molded with each other. The first lens portion is disposed between the image display unit and the reflecting unit. The second lens portion is disposed between the reflecting unit and the eye. The image light beam is transmitted to the eye through the first lens portion, the reflecting unit, the second lens portion and the diffractive optical element to provide a virtual image. Besides, a virtual image display module is also provided.

Abstract: A virtual image display module, disposed in front of at least one eye of a user, including an image displaying unit and an optical lens group is provided. The image displaying unit provides an image beam. The optical lens group includes a reflecting unit, a first lens, a second lens and a diffractive optical element, which are disposed on the transmission path of the image beam. The first lens is disposed between the image displaying unit and the reflecting unit. The reflecting unit is disposed between the first lens and the second lens. The second lens is disposed between the reflecting unit and the eye. The diffractive optical element, the reflecting unit, the first lens and the second lens are independent optical elements, respectively. The image beam is transmitted to the eye through the first lens, the reflecting unit, the second lens and the diffractive optical element.
