A display device is disclosed. The display device includes a display panel, a backlight unit for emitting light to the display panel, a backlight driving part for driving the backlight unit, a storage part for storing a gamma curve indicating a relationship between the gradation of an input signal inputted to the display panel and the luminance of an output signal, and a processor for reducing the brightness of light emitted to the display panel by a difference between a first output luminance value, which is the maximum luminance value of the display panel, and a second output luminance value of the input signal. Here, the second output luminance value may be an output luminance value corresponding to the maximum gradation value of the input signal in the gamma curve. It is possible to drive a backlight with global dimming while maintaining the gamma curve.
