Abstract
An augmented reality display device configured to be disposed on a head of a user includes a display, a relay lens set, a beam splitting module, and a curved mirror. The display is configured to emit an image beam. The relay lens set is disposed on a path of the image beam. The beam splitting module is disposed on a path of the image beam from the relay lens set. The curved mirror is configured to reflect the image beam from the beam splitting module back to the beam splitting module. The image beam reflected by the curved mirror penetrates through the beam splitting module and is then transmitted to a pupil of the user. The beam splitting module includes a polarizer, a brightness enhancement film, and a phase retardation film stacked together in sequence from a side adjacent to the pupil to a side adjacent to the curved mirror.
