    Abstract: According to one embodiment, a display device includes a display panel including a gate line, source lines, and switching elements connected to the gate line and the respective source lines. A gate driver selects the gate line. A source driver supplies an image signal to the source lines. The image signals can be supplied to pixel electrodes through the switching elements. A frame period includes a first scan period in which the gate line is selected, a first hold period subsequent to the first scan period, a second scan period in which the gate line is selected subsequent to the first hold period, and a second hold period subsequent to the second scan period. The first hold period is longer than the second hold period.

    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.

    Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer, a first alignment film, a pixel electrode, and a common electrode. The liquid crystal layer is disposed between the first substrate and the second substrate. The first alignment film is provided on the first substrate to be in contact with the liquid crystal layer. The pixel electrode is provided on the first substrate and covered with the first alignment film. The common electrode provided on the first substrate to form a lateral electric field. The liquid crystal layer is driven at a frequency of 40 Hz or less. A time constant of the liquid crystal layer is larger than a time constant of the first alignment film.
