Abstract: An image display device includes an imaging element, a light source that forms a floating image, a position detecting part, a driver, and a controller. The imaging element includes a base member including a first surface, and a reflector array on the base member; or a base member comprising a reflector array and including a first surface. The reflector array includes multiple reflector rows including multiple dihedral corner reflectors along a first direction. The reflector rows are arranged parallel to a second direction crossing the first direction. The dihedral corner reflectors each include a first reflecting surface, and a second reflecting surface orthogonal to the first reflecting surface.

Abstract: An image display device includes: an imaging element; a light source configured to irradiate light toward the imaging element; a light-shielding member configured to shield a portion of light of at least the light source; and a light-transmitting member configured to transmit light emitted from the imaging element, the light-transmitting member selectively controlling a transmission of light of at least some wavelengths of the light emitted from the imaging element.
