    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 liquid crystal display device includes a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a first electrode, a stage including an electrode formation surface, a switching element, a second electrode and a first vertical alignment film. The second substrate includes a third electrode and a second vertical alignment film. The electrode formation surface is positioned closer to the second substrate than a portion of the first vertical alignment film, which opposes the first electrode.

    Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a sealant, a liquid crystal layer, an organic insulating film, an alignment film and an inorganic insulating film. The second substrate is opposed to the first substrate. The sealant attaches the first substrate and the second substrate to each other. The liquid crystal layer is arranged between the first substrate and the second substrate. The organic insulating film, the alignment film and the inorganic insulating film are provided on the first substrate. The alignment film contacts the liquid crystal layer. The inorganic insulating film is located between the alignment film and the organic insulating film. At least pan of the alignment film contacts the organic insulating film.
