Abstract:
A surface illumination device is provided with a laser light source capable of emitting a laser light, an incident surface on which the laser light is incident, a light guiding plate having a principal surface from which the laser light emerges as a surface emergent light, and an irradiating member capable of irradiating the laser light from the laser light source over a specified range extending in the longitudinal direction of the light guiding plate.
