Abstract: When normal driving is switched to intermittent driving simultaneously with switching from a video image to a still image, a flicker may occur due to a response delay caused by dielectric anisotropy of liquid crystal. A display device has a first mode (video image driving) in which driving is performed at a first frame frequency and a second mode (still image driving) in which the driving is performed at a second frame frequency lower than the first frame frequency. When the first mode is switched to the second mode, the display device first performs the driving at a frame frequency higher than the second frame frequency for at least one frame and then, the driving is switched to be performed at the second frame frequency.
