Backlight unit with coupling hole and liquid crystal display having the same

摘要

A backlight unit and a liquid crystal display having the same. The backlight unit includes a lower cover, an interconnection coupling hole, an inverter board, and an interconnection. The lower cover accommodates a printed circuit board, which mounts at least one light emitting diode thereon and is provided at one side thereof with a first connector. The interconnection coupling hole is formed in a bottom surface of the lower cover at a position corresponding to the first connector. The inverter board is disposed on a rear surface of the lower cover to apply a driving voltage to the at least one light emitting diode. The interconnection is provided at one end thereof with a second connector to electrically connect the printed circuit board to the inverter board. A coupling part of the first connector coupled to the second connector is directed to the interconnection coupling hole, so the assembling time of the backlight unit and the liquid crystal display is reduced, thereby improving the productivity of the backlight unit and the liquid crystal display.
