Abstract
The disclosure discloses a near-to-eye display device, including: a first display screen, a first imaging lens, a second display screen, a second imaging lens and a waveguide. The first display screen provides a first image and the first image enters the waveguide through the first imaging lens. The second display screen provides a second image, the second image enters the waveguide through the second imaging lens. Imaging light rays from the first imaging lens and the second imaging lens can emit towards a light-emitting surface of the waveguide via a light taking part, and enter the human eyes.
