Document Type and Number:
Japanese Patent JP6604282
Kind Code:
B2
Abstract:
An optical device includes a light guide plate configured to guide light within a plane parallel to an emission surface, and a plurality of deflectors configured to deflect light guided thereto by the light guide plate, causing light forming an image in a space outside the light guide plate to exit from the emission surface. Each deflector in the plurality of deflectors cause the light to exit from the emission surface toward a direction substantially converging onto a single convergence point or convergence line in the space, or to substantially radiate from a single convergence point or convergence line in the space. The convergence point or the convergence line is mutually different among the plurality of deflectors with a grouping of a plurality of the convergence points or the convergence lines forming the image in the space.
