Abstract: A light guide plate has a light incident surface configured to be arranged facing a point light source for introducing light from the point light source, a light outputting surface that outputs the light to an outside of the light guide plate, a light introducing section for confining the light from the point light source entered from the light incident surface, and a light guide plate main body having a thickness smaller than a maximum thickness of the light introducing section and being arranged to be continuous with the light introducing section, for outputting the confined light to the outside of the light guide plate from the light outputting surface by a light outputting element.

IPC: F21V8/00

Abstract: An optical device has a light guide plate configured to guide light within a plane parallel to an emission surface thereof, and a plurality of optical deflectors arranged two-dimensionally within a plane parallel to the emission surface. Each of the optical deflectors deflects light propagating through the light guide plate, and causes the emission surface to output light forming an image in a space. Each of the optical deflectors is configured to spread the light incident thereon that has an intensity distribution corresponding to an image in a direction orthogonal to the light guide direction of the light guide plate in a plane parallel to the emission surface, and cause the emission surface to output the light which groups the light from the plurality of optical deflectors arranged along a direction orthogonal to the light guide direction, such that light radiating from the image is formed.
