Abstract: A backlight unit and an LCD(Liquid Crystal Display) device are provided to prevent the leakage of a tube current by forming equalized potential by a coil, which is connected to portions adjacent to the inverter of lamps while surrounding the portions and of which both ends are connected to a bottom cover, so that the lamps can maintain the same tube current irrespective of the position of the lamps and generate the uniform brightness by the same tube current. A backlight unit(50) has plural lamps(55), a bottom cover(52) and an optical member(54). One side part of the plurality of lamps is connected by a coil(57). The upper part of the bottom cover is opened and the lamps are arranged within the inner space. The optical member is arranged on the lamps. The coil is connected to the bottom cover. The one side part is a portion adjacent to an inverter.
