Abstract: According to one embodiment, a liquid crystal display device includes an array substrate, a counter substrate, a liquid crystal layer and a driving unit. The driving unit is configured to perform polarity inversion driving by applying, to the pixel electrode, positive and negative video signals. When applying the video signals to the pixel electrode, the driving unit superposes a correction signal corresponding to a polarity inversion frequency and the gray level on the video signals in advance.

Abstract: An object of the present invention is to realize a liquid crystal display device having a photo-aligned alignment film in which the alignment film is overlapped with a seal material to downsize a frame area, and the reliability of a seal portion can be secured. A first alignment film and a second alignment film are overlapped with a seal material, the first alignment film and the second alignment film are made of material containing 0.5 wt % or larger and 2 wt % or smaller of an amine-system silane coupling agent, and the shrinkage ratio and the storage elastic modulus of the seal material evaluated using the modulus of volume change by a specific gravity cup method are 5.1% or smaller and 9.2 Pa or smaller, respectively. Accordingly, a frame area can be downsized, and the reliability of a seal portion can be maintained.

Abstract: According to one embodiment, the organic insulating film and the alignment film are provided on the first substrate. The alignment film is located between the liquid crystal layer and the organic insulating film and contacts the liquid crystal layer. The organic insulating film has a restricting portion on an inner side from the sealant and on an outer side from the display area. The restricting portion includes a recess and a projection extending in predetermined directions. The alignment film is formed on the restricting portion.

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: 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.
