Abstract
In a spread Illuminating apparatus basically comprising a light conductive plate and a lamp, the lamp comprises at least two light conductive bars and a spot-like light source disposed on one or both end surfaces of the light conductive bars, and is disposed close a side surface of the light conductive plate. An optical path conversion means comprising grooves and flat portions is formed on a side surface of each of the at least two light conductive bars. Light-and-dark striping generated on the light conductive plate by light reflected by one optical path conversion means of one light conductive bar of the at least two is corrected by light reflected by the other optical path conversion means of the other light conductive bars.
