In a display device and a method of driving the display device each having an improved image display quality, the display device includes the display panel assembly, a light emitting unit and a control unit. The display panel assembly has a plurality of unit pixels and displays an image. The light emitting unit is disposed under the display panel assembly to supply light to the display panel assembly, and has a plurality of light emitting diodes ("LEDs") corresponding to a unit pixel group including a given number of the unit pixels. The control unit is electrically connected to the display panel assembly and the light emitting unit, and controls the unit pixels by arbitrary regions and the LEDs by arbitrary regions. Thus, a contrast ratio of the display device is increased to improve image display quality.
