The image beam exits the waveguide substrate via the light exiting surface after one or more reflections. The first and second optical film structures are respectively arranged on the first and second sides. The sub-wavelength nanostructure arranged on the first side can receive and diffract the image beam to couple the image beam to the waveguide substrate. The first and second optical film structures can reflect the part of the image beam at the incident angle smaller than the critical angle of the waveguide substrate.
