ABSTRACT:
An illumination device includes an optical waveguide that has light incident end faces formed at both ends thereof; and light sources that are disposed on the light incident end faces formed at both ends of the optical waveguide. A reflective surface of the optical waveguide has first and second reflective surfaces intersecting at a predetermined boundary line, and a light-emitting surface of the optical waveguide has first and second regions divided by the predetermined boundary line. When the light sources provided at one end of the optical waveguide are turned on, light is emitted such that one of the first and second regions is brighter than the other.
