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.

Claim (Index 2):
The optical device according to  claim 1 , wherein\n both ends of the light guiding member are formed to be oblique with respect to the longitudinal direction, the diffraction gratings are disposed on both end faces of the light guiding member, respectively, and each of the diffraction gratings is obliquely disposed so that light transmitted through the diffraction grating disposed on an entering side of the optical device is reflected in a region of the light guiding member where the diffraction grating is not disposed.
