LIGHT SOURCE DEVICE

PROBLEM TO BE SOLVED: To provide a light source device capable of obtaining a desired planar light source. SOLUTION: A plural kinds of light-emitting diodes 39 to 41 for irradiating white light on a liquid crystal display part 20 are constituted of light-emitting diode elements emitting a first emis...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light source device capable of obtaining a desired planar light source. SOLUTION: A plural kinds of light-emitting diodes 39 to 41 for irradiating white light on a liquid crystal display part 20 are constituted of light-emitting diode elements emitting a first emission light directed toward a reflector 33 correspondent to each out of the plurality of reflectors 33 and a second emission light expanding the irradiation light from the reflector 33 to which the first emission light is directed. For this, the emission light from the light-emitting diode lamp 37 is irradiated so as to spread from the reflector 33. COPYRIGHT: (C)2007,JPO&INPIT
