Abstract: A display device includes light sources that emit light, a display panel that displays an image, and a light guide panel that guides the light emitted from the light sources to the display panel. The light guide panel includes an incident surface facing the light sources, an emission surface facing the display panel, a first reflective surface facing the incident surface, and a second reflective surface facing the emission surface. The first reflective surface has a concave shape that reflects light so that the reflected light becomes closer to parallel light when viewed in a facing direction of the display panel and the light guide panel in the light guide panel, is tilted at an angle larger than 0 degrees with respect to the incident surface, and intersects the second reflective surface at an angle smaller than 90 degrees.

Abstract: An imaging apparatus includes: a reflector which covers an imaging space on a pathway that a human passes through, from at least one of both sides of the pathway, and diffusely reflects a sub-terahertz wave; a first light source which emits a sub-terahertz wave onto the reflector; and a first detector which receives a reflected wave of the sub-terahertz wave emitted from the first light source, diffusely reflected by the reflector, and reflected by the human, and generates an image based on the reflected wave received. The first light source and the first detector are located at a first direction side relative to a center of the imaging space in a direction in which the pathway extends.

Abstract: A display device includes a display panel and a lighting device. The lighting device includes a light source, a light guide panel including an emission surface from which a light of the light source is emitted toward the display panel, a first optical member including a prism array opposing the emission surface of the light guide panel, and a second optical member provided with a Fresnel lens on a surface opposing the emission surface of the first optical member, As viewed in a first direction orthogonal to a normal direction of the display panel, the Fresnel lens emit a light passing through a center of a transmissive region of the display panel in a direction inclined at a fifth angle with respect to the normal direction and bigger that a fourth angle between the display panel and the emission surface of the light guide panel.

Abstract: An image display apparatus includes a display panel, and a liquid crystal lens disposed in front of the display panel. The liquid crystal lens includes: a first substrate and a second substrate; a first electrode layer; a second electrode layer having a plurality of electrodes formed in a stripe pattern; and a liquid crystal layer in which the direction of orientation of liquid crystal molecules is changed in accordance with an applied voltage. In the second electrode layer, the plurality of electrodes extend in a direction inclined with respect to black lines extending in a predetermined direction in a black matrix. The direction of initial orientation of the liquid crystal molecules is substantially parallel to a transmission axis of a front-surface-side polarizing plate.

Abstract: The present disclosure provides an image display that includes a light source unit, a display panel that displays image, and a light guide panel that guides light emitted from the light source unit to the display panel. The light guide panel has an incident surface facing the light source unit, an output surface facing the display panel, and a bottom surface facing the output surface on a side opposite to the display panel. The incident surface is a side surface of the light guide panel located between the output surface and the bottom surface. The incident surface has a concave portion in which a part of the incident surface is recessed from remaining portions when viewed from a direction perpendicular to a light guide direction of light in the incident surface and an emission direction of light in the output surface.

Abstract: A head-up display includes a light source unit including first light source elements emitting lights of a first luminescent color and second light source elements emitting lights of a second luminescent color. The head-up display includes a first lens, a diffusion member, a spatial light modulation element that modulates the light emitted from the light source unit and transmitted through the first lens and the diffusion member, and an optical unit that projects the light emitted from the spatial light modulation element. The first lens changes an optical path of the light emitted from the light source unit, and the lights emitted from the first light source element and the second light source element are superimposed in a predetermined region on the incident surface of the spatial light modulation element.
