Abstract

Land portions to which the spot-like light source is soldered are provided at the end of the FPC, whereby the light emitting surface of the spot-like light source is aligned to the side of the FPC, that is, the FPC does not protrude from the light emitting surface. The spot-like light source mounted on the FPC is disposed close to the light conductive bar with its light emitting surface facing the end surface of the light conductive bar. Since the FPC does not exist ahead of the light emitting surface, the FPC does not overlap the end portion of the light conductive bar, so that light rays emitted from the light emitting surface do not irradiate the FPC.
