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.

Waveguide-type display device

A retinal projection display device is provided. The retinal projection display device includes a light source configured to emit light, a spatial light modulator configured to generate diffracted light by diffracting the emitted light, a holographic optical element configured to reflect the diffracted light by duplicating the diffracted light into a plurality of complex wavefronts, and a field lens configured to focus the plurality of complex wavefronts to a plurality of respective focal points in an eye-box, wherein the plurality of complex wavefronts overlap each other.
