There is disclosed a liquid crystal display (LCD) device that prevents degeneration of a displaying performance due to heat generated in the LCD. A heat shielding thin film of an aluminum-contained material, which is disposed in a receiving container, shields the heat additionally generated during a converting process of power for driving a lamp in an inverter module, thereby minimizing the heat to be transferred to a reflector panel. Therefore, the heat generated during a process of producing light is efficiently blocked and discharged, thereby minimizing the degeneration of displaying characteristic.

1. A liquid crystal display (LCD) device, comprising:an LCD panel assembly for controlling a liquid crystal to display an image; a backlight assembly provided with a lamp assembly for supplying light to the LCD panel assembly and a light uniformity-enhancing module for improving uniformity of the light generated from the lamp assembly; a receiving container for receiving and fixing the LCD panel assembly and the backlight assembly; an inverter disposed at an outer surface of the receiving container to supply power needed to drive the lamp assembly; and a heat shielding unit disposed at the receiving container corresponding to a portion between the inverter and the light uniformity-enhancing module so as to shield heat generated from the inverter and to reduce heat transmission to the light uniformity-enhancing module. 2. The LCD of claim 1, wherein the heat shielding unit comprises a conductive plate.3. The LCD of claim 2, wherein the heat shielding unit comprises aluminum.4. The LCD of claim 2, wherein the heat shielding unit comprises a first metal thin film bonded to a second metal thin film by an adhesive material.5. The LCD of claim 4, wherein the first metal thin and the second metal thin film have different thicknesses.6. The LCD of claim 5, wherein the first metal thin film is adjacent to the backlight assembly and is thicker than a second film of the metal thin films.7. The LCD of claim 1, wherein the heat shielding unit has a greater surface area than a surface area of the inverter.8. The LCD of claim 7, wherein the heat shielding unit has a surface area that is about twice as large as a surface area of the inverter.9.
