Abstract

Provided is a waveguide-type display device including a waveguide, an input coupler provided on the waveguide and configured to transmit an image to travel into the waveguide, an output coupler provided on the waveguide and configured to output the image traveling in the waveguide to an outside of the waveguide, and a field-of-view (FOV) expander configured to output an image having an expanded FOV by deflecting and outputting the image output from the output coupler in a certain direction based on polarization characteristics of the image.
