Abstract: A light refraction member includes an incident surface on which planar light is incident, a plurality of refractors that refract the planar light, and an emitting surface from which the planar light refracted by the plurality of refractors is emitted as emitted light. The plurality of refractors are provided side by side in a first direction on at least one of the incident surface and the emitting surface, and each of the plurality of refractors has an area in which a direction in which the planar light is refracted changes along a second direction intersecting the first direction.

Abstract: Light control body (6) has first incident surface (7) and first reflection surface (9). First incident surface (7) condenses part of light emitted from light source (1) and emits the light toward incident surface (3) of light guide plate (2). First reflection surface (9) reflects the light that is emitted from light source (1) and does not pass through first incident surface (7), and emits the light toward incident surface (3) of light guide plate (2). First focal position (11) of first incident surface (7) and second focal position (12) of first reflection surface (9) are set at positions that are different from each other and away from the light emission surface of light source (1).

Abstract: An optical system includes a light guide member, a prism, and a plurality of light control bodies. The light guide member includes an incident surface on which light is incident, and a first surface and a second surface facing each other. In the light guide member, the second surface is an emission surface of light. The prism is provided on the first surface and reflects light passing through the light guide member toward the second surface. The plurality of light control bodies are positioned between light sources and the incident surface. The plurality of light control bodies control light rays output from the light sources and incident on the incident surface. Each of the plurality of light control bodies includes an incident lens. Each of the plurality of light control bodies causes the light incident on the incident lens from the light source to be incident on the incident surface.

Abstract: An optical system includes a light guide member and a plurality of prism pieces. The light guide member has an incident surface on which light is incident, and first and second surfaces facing each other, and the second surface is a light-emitting surface. The plurality of prism pieces are provided on the first surface and reflect the light passing through an inside of the light guide member toward the second surface. The plurality of prism pieces include two or more prism pieces having different inclination angles with respect to an incident surface depending on a position in at least a first direction along both the incident surface and the first surface. The inclination angles of two or more prism pieces are determined so that the light emitted from the second surface is directed to the outside or the inside of the first direction with respect to a reference light beam as the prism piece is positioned closer to both ends of the first surface in the first direction.
