Abstract:
1. A lighting device for a display device, comprising: a plurality of linear light sources arranged parallel to one another so as to emit light to a light emitting side; and a light reflecting plate arranged on a back side of said plurality of linear light sources that corresponds to an opposite side of said light emitting side, wherein: a first angled reflective portion having an angled section is provided on said light reflecting plate, so as to be positioned between adjacently-arranged linear light sources of said plurality of linear light sources; said first angled reflective portion includes a first inclined surface and a second inclined surface as light reflecting surfaces, so that said first inclined surface faces a center side of an array of said plurality of linear light sources while said second inclined surface faces an outer side of the array of said plurality of linear light sources; a second angled reflective portion having an angled section is provided on said light reflecting plate, so as to be positioned between adjacently-arranged linear light sources of said plurality of linear light sources and closer to a center of the array of said plurality of light sources than said first angled reflective portion; said second angled reflective portion includes a third inclined surface and a fourth inclined surface as light reflecting surfaces, so that said third inclined surface faces the center side of an array of said plurality of linear light sources while said fourth inclined surface faces an outer side of the array of said plurality of linear light sources; and an inclination angle of said first inclined surface is set to be larger than an inclination angle of the third inclined surface.
