Abstract: Provided is an optical device which increases design flexibility. An optical device includes: a light guiding unit, the cross-section of which is approximately trapezoidal; and diffraction gratings disposed in the light guiding unit. The diffraction gratings are obliquely disposed with respect to the longitudinal direction of the light guiding unit. A signal that is output from a micro-projector (light source) enters the diffraction grating, light that is diffracted by the diffraction grating is reflected by a reflecting unit, the reflected light is diffracted by the diffraction grating and enters an eye.
