    Abstract: According to an aspect, a display device includes: a display panel; a first optical component serving as a switchable optical component capable of being switched between a reflection state and a transmission state of light by a reflection surface thereof; and a second optical component. The reflection surface of the first optical component that faces the display panel is arranged on a light path extending from the display panel. The second optical component has a reflection surface. The reflection surface of the second optical component is on a path of light reflected by the first optical component.

    Abstract: According to one embodiment, an illumination device includes a light source, clad, and a plurality of cores. The clad includes a first edge at a light source side, a second edge opposite to the first edge, and a plurality of grooves formed by a plurality of partitions extending in parallel to each other from the first edge to the second edge. The cores are accommodated in the grooves, and each core includes an incident surface on which light from the light source is incident and an exit surface exposed from the groove to emit the light incident on the incident surface.
