| description | A surface light source device includes a first light source for emitting first light, a first light guide rod for causing the first light to be incident thereon and converting the first light into first linear light, a second light source for emitting second light having a greater divergence angle than the first light, and a second light guide rod for converting the second light into second linear light extended in the same direction as the first linear light. Moreover, the surface light source device includes a reflecting bar disposed on an emitting side of the planar light from the first and second light guide rods, and a reflecting portion taking such a box shape as to have an internal wall serving as a reflecting surface, and having an opening portion on a surface at the emitting side of the planar light. |
