    Abstract: An image display device includes an imaging element and multiple light sources. The imaging element reflects light of the multiple light sources and forms multiple floating images in mid-air. The imaging element includes a base member including a first surface, and a reflector array on the base member. The reflector array includes multiple reflector rows including multiple dihedral corner reflectors along a first direction. The multiple reflector rows are arranged parallel to a second direction crossing the first direction. The multiple 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, a detecting part, and a controller. The imaging element includes a base member including a first surface, and a reflector array on the base member. The reflector array includes multiple reflector rows, each including multiple dihedral corner reflectors along a first direction. The multiple reflector rows are arranged parallel to a second direction crossing the first direction. The multiple dihedral corner reflectors each include a first reflecting surface, and a second reflecting surface orthogonal to the first reflecting surface. A tilt of a second orthogonal reflector is set to form a floating image at the first surface side. The light-transmitting member is arranged to transmit twice-reflected light of the imaging element. The light-shielding member shields a portion of light other than the twice-reflected light.

    Abstract: A light emitting device includes a substrate, a light source, and a covering member. The light source has an optical axis, a light source bottom portion and a light source upper portion opposite to the light source bottom portion in the optical axis. The light source is provided on the substrate at the light source bottom portion. The covering member has a bottom surface and a top portion opposite to the bottom surface in the optical axis and is provided on the substrate at the bottom surface to cover the light source. The covering member has a recess portion on the top portion above the light source and around the optical axis. The covering member tapers toward the bottom surface.
