Abstract
A backlight unit capable of preventing its mis-operation and the generation of sparks due to electrical connection defects is disclosed. The backlight unit includes: a plurality of lamps emitting lights; a lamp printed-circuit board including a power supply portion electrically connected to the plural lamps and a connector wiper transferring a drive voltage to be applied to the power supply portion; a connector including a connector housing, engaged with the connector wiper and electrically connected to the connector wiper, and wires electrically connected to the connector housing; and another printed-circuit board, electrically connected to the wires, applying the drive voltage to the lamp printed-circuit board. The connector housing includes stoppers extruded toward the lamp printed-circuit board. The stoppers prevent a contact defect of the connector wiper and the lamp printed-circuit board which is caused by the connector housing.
