A backlight unit and a display device are provided. The duty or the like of a light source driving signal is adjusted so that a frequency component causing flicker to be visible, among frequency components of luminance appearing in a driving period of low-speed driving mode. Flicker is prevented or reduced in the low-speed driving mode. The display device is driven in the low-speed driving mode to reduce power consumption. The display device is driven at a lower display driving frequency in the low-speed driving mode, thereby improving the efficiency thereof.
