The image generation unit 12 is used for generating an image a to be displayed. The optical imaging unit 13 is a transmissive imaging element, and specifically, the optical imaging unit 13 is a lens group. The optical imaging unit 13 transmits image light of an image to be displayed, the light beam of the image light transmitted by the optical imaging unit 13 is an imaging light beam, and an enlarged virtual image b is formed on a reverse extension line of the imaging light beam. The imaging light beam enters the display window 11 and is reflected by the display window 11 towards the user's eye. The enlarged virtual image b is thereby mirror-imaged through the display window 11, and a virtual image c, which is as large as the virtual image b, is formed on the side of the display window 11 facing away from the eyes of the user, which virtual image c can be viewed by the eyes of the user through the display window 11. It should be noted that, in this embodiment, in order to form the enlarged virtual image b on the reverse extension line of the imaging light beam, the distance between each point on the image to be displayed a generated by the image generation unit 12 and the optical imaging unit 13 needs to be smaller than the equivalent focal length of the optical imaging unit 13.
