Abstract: A display device comprises a liquid crystal panel including a plurality of pixels and an imaging device arranged on a back side of the liquid crystal panel. The imaging device has an imaging region overlaps with the imaging device and the other region other than the imaging region in a plan view. A plurality of linear electrodes is arranged separately from each other in the imaging region. Among the plurality of linear electrodes, a first pair of linear electrodes are separated by a first interval and a second pair of linear electrodes are separated by a second interval different from the first interval in a plan view. The first pair of linear electrodes and the second pair of linear electrodes are irregularly arranged.

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 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.
