Abstract: A display device includes a beam generator and a holographic optical waveguide. The beam generator includes a display and is configured to generate beams having image information displayed on the display. The holographic optical waveguide is configured to display an image of a second size at a position at a first distance behind the display device based on the beams having the image information, the second size is a multiple of the first size of the display, and the multiple is greater than 1.
