A head-up display device (HUD) of the present invention displays driving information of all kinds of vehicles on the front glass of a vehicle by using a high luminance light emitting diode (LED) as a light source and improves heat radiation effects by discharging heat generated by the LED to a lower heat radiation fan unit by forming a plurality of holes on the one lower side of a LED housing for radiation. The HUD comprises: a liquid crystal panel which outputs an image; a guide mold which is located on the rear side of the liquid crystal panel and stores the liquid crystal panel; a plurality of LEDs which is arranged on the lower side of the liquid crystal panel and supplies light to the liquid crystal panel; an LED printed circuit board wherein the LEDs are mounted; and a LED housing which is located on the lower side of the guide mold and combined with the guide mold and the LED printed circuit board is combined with the lower side of the LED housing; a heat radiation fan unit which is located on the lower side of the LED housing and discharges a heat generated in the LEDs to the outside. The holes are formed on at least one lower side of the LED housing, thereby discharging the heat generated in the LEDs to the lower heat radiation fan unit. |
