  • Image display device
    Patent number: 10330943
    Abstract: An image display device includes a half mirror, an image output device configured to output a light beam to one face of the half mirror, and a retroreflective member configured to retroreflect at least one of a light beam mirror-reflected off the one face of the half mirror and a light beam transmitted through the one face of the half mirror. The retroreflective member has a base material layer and a plurality of prismatic retroreflective elements formed on one face or two faces of the base material layer. The tilt angle of the optical axis of the prismatic retroreflective element exceeds zero degree.
    Type: Grant
