Provided is a display device with which, while alleviating degradation of display quality and liquid-crystal deterioration, it is possible to switch refresh rates. When switching the refresh rate from 60Hz to 7.5Hz, a transition period is disposed between the 60Hz period to the 7.5Hz period for changing the refresh rate in stages from 60Hz to 7.5Hz. The transition period is configured of the 30Hz period, the 20Hz period, the 15Hz period, the 12Hz period, and the 10Hz period, in order from the commencement time of the transition period. Thus, the refresh rate is changed in stages from 60Hz through the sequence of 30Hz, 20Hz, 15Hz, 12Hz, and 10Hz to 7.5Hz. The number of positive polarity frames and the number of negative polarity frames in the overall transition period is 20, respectively, and are both equal to each other. |
