The present invention relates to a liquid crystal display device, particularly, to a backlight unit for a liquid crystal display device. The first and second LED assembly, the present invention is to divide the defined first and second light guide plate and the first and supply the light from the opposite side surfaces of the first and second light guide plate to divide the defined area of the second light guide plate into a plurality of areas the via, at the same time to provide a uniform surface light source to the liquid crystal panel with a thin it is possible to provide a backlight unit of a low power consumption. And, it is possible to prevent the lamp unevenness (mura) symptoms, the luminance can be uniform and provide a liquid crystal display device and the display quality is improved. Further, the it is possible to provide light for each of the divided regions defined by the first and second light guide plate to the liquid crystal panel, it is possible to improve the contrast ratio (contrast ratio) of the liquid crystal display device. Thus, it is possible to implement a more lifelike image. In addition, it is possible to reduce the power consumption. LED, light guide plate, a lamp-mura, contrast ratio, and power consumption
