Abstract:
A glasses-type device can include a display part configured to emit image light serving as an image source of a virtual image; a diffraction element configured to reflect and diffract the image light at a predetermined angle; and a first holographic optical element disposed on at least a portion of glass of the glasses-type device, in which the first holographic optical element is configured to cancel dispersion of the image light that is reflected and diffracted by the diffraction element, and reflect the light in which dispersion is canceled to display a virtual image corresponding to the image light.
