Abstract:
1. A light-emitting-diode backlight device comprising: a light source substrate to which a plurality of light-emitting diodes are mounted; and a bottom chassis having the light source substrate mounted to a principal surface side of the bottom chassis, wherein illumination light emitted from each of the light-emitting diodes at the light source substrate is supplied to a display panel unit, wherein a back-surface side of the bottom chassis is provided with heat-dissipating means which makes uniform a temperature distribution over the entire bottom chassis, and wherein the heat-dissipating means includes a mounting plate, a heat pipe, and a radiating fin, the mounting plate being mounted directly to at least a high-temperature area of the bottom chassis, the heat pipe being disposed on both the high-temperature area and a low-temperature area of the bottom chassis and being mounted to the mounting plate, the radiating fin being mounted directly to the low-temperature area and being directly connected to an end of the heat pipe.
