Abstract

The illuminating apparatus of the present invention has two light conductive bars which have one spot-like light source in common on their end surfaces, and which are disposed with their respective side surfaces facing each other and along the end surface of a light conductive plate. The spot-like light source has the center of its light emitting surface positioned to an interface portion between the two light conductive bars, whereby non-uniformity in brightness of lights at the end surfaces of the light conductive bars is diminished at the end surface of the light conductive plate with respect to the length direction of the light conductive bars while the lights emitted from the spot-like light source and introduced into the light conductive bars have their optical paths changed at respective optical path conversion means formed on the light conductive bars, and travel into the light conductive plate.
