The present invention relates to a display device which can be driven using lower power consumption. The display device comprises a display panel, a timing controller, a backlight unit, and a backlight control unit. The display panel comprises a plurality of display blocks, receives an image signal, and displays an image. The timing controller receives the image signal including block image signals corresponding to the respective display blocks. The backlight unit comprises ″a″ red light sources, ″b″ green light sources (″a″ and ″b″ are natural numbers, and ″b″<″a″), and ″a″ blue light sources, and provides light to the display panel. The backlight control unit calculates average red luminance, average green luminance, and average blue luminance of the respective block image signals, controls a duty ratio of the red light sources based on the average red and green luminance, controls a duty ratio of the green light sources based on the average green luminance, and controls a duty ratio ...
