PURPOSE:To prevent temperature rise in a device by improving the reflection efficiency of the light from an emitter, and by radiating the heat at the time of emission on the outside of a backlight device. CONSTITUTION:An emitter 6 is arranged on a reflecting plate, and the light emitted from an emitter 5 to the entire periphery is effectively reflected in the direction of a display plate 1. The heat emitted from the emitter 6 is effectively conducted to the reflecting plate by bringing the emitter 6 into contact with the reflecting plate 4. Heat radiation on the outside of a backlight device is carried out by extending the reflecting plate made of Al, Cu, etc., of high heat conductivity to the outside of the backlight device. |
