Abstract: According to one embodiment, a display device includes scanning lines, a first signal line crossing the scanning lines, a first pixel electrode electrically connected to the first signal line, and a common electrode opposed to the first pixel electrode. In a frame period having a writing period where the scanning lines are sequentially selected and a holding period where the scanning lines are in an unselected state, polarity of a potential of the first signal line is first polarity in the writing period, and is reversed to second polarity different from the first polarity midway through the holding period.

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 part of the alignment film contacts the organic insulating film.
