Abstract
A liquid crystal display device includes: a light emitting diode array unit including at least two groups of light emitting diode arrays for emitting light; a light emitting diode driving unit for supplying at least two pulse width modulation signals having different phases from each other to the at least two groups of light emitting diode arrays, respectively; a liquid crystal display panel for displaying images using the light from the light emitting diode array unit; and a timing controller for controlling the light emitting diode driving unit and the liquid crystal display panel.
