摘要： According to one embodiment, a display device includes a first substrate, a second substrate facing the first substrate and a liquid crystal layer. The first substrate includes a base material, and a sensor which outputs a detection signal based on incident light from a liquid crystal layer side. The sensor includes a photoelectric conversion element including a first surface and a second surface, a first electrode which is in contact with the first surface, and a second electrode which is in contact with the second surface. Each of the photoelectric conversion element and the second electrode is formed in an irregular shape having a plurality of curved portions and a plurality of straight portions connecting the curved portions as seen in plan view.

摘要： In an IPS mode liquid crystal display device, measures are taken against dark unevenness at the corner portion of a screen. The problem can be solved by a liquid crystal display device in which a comb tooth pixel electrode is formed on a common electrode formed in a flat surface through an interlayer insulating film; a TFT substrate is formed with a dummy pixel region and a display region surrounding the display region; a pixel on the display region is formed with a comb tooth display region pixel electrode bent in a projection in the first direction; and a pixel on the dummy pixel region is formed with a comb tooth dummy pixel region pixel electrode bent in a projection in a direction opposite to the first direction at an angle of 180 degrees.
