Abstract:
A light control body (6) has a first incident surface (7) and a first reflection surface (9). The first incident surface (7) collects a portion of light emitted from a light source (1), and outputs the light to an incident surface (3) of a light guide plate (2). The first reflection surface (9) reflects light that has been emitted from the light source (1) but has not passed through the first incident surface (7), and outputs the light to the incident surface (3) of the light guide plate (2). A first focus position (11) of the first incident surface (7) and a second focus position (12) of the first reflection surface (9) are set at different positions that are distant from a light emission surface of the light source (1).
