A light emitting diode backlight unit and a liquid crystal display device
having the same is provided. The light emitting diode improves efficiency
of a backlight and productivity by mounting light emitting diodes and
drive components onto the same printed circuit board. The light emitting
diode (LED) backlight unit includes a printed circuit board, a plurality
of light emitting diodes mounted onto the printed circuit board, a
plurality of drive components mounted onto the printed circuit board and
driving the light emitting diodes and a control unit electrically
connected with the printed circuit board and controlling the drive
components.
