Original Abstract Submitted
There is provided an image display device capable of displaying more information by enlarging a display angle-of-view region while suppressing color unevenness with a simple configuration. An image display device includes: an image forming unit that has a plurality of pixels and emits image light from the plurality of pixels; an optical system that converts each beam of the image light having an image height emitted from the image forming unit into a parallel beam having an angle of view; a light guide plate on which the image light converted by the optical system is incident, in which the image light propagates, and from which the image light is emitted to the outside; a first diffraction grating that is provided on the light guide plate, diffracts and reflects the image light incident on the light guide plate, and propagates the image light inside the light guide plate; and a second diffraction grating that is provided on the light guide plate, diffracts and reflects the image light that has propagated inside the light guide plate, and emits the image light from the light guide plate to the outside. The image forming unit divides the image light into a plurality of color beams.
