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 line, a second line, a switching element, a common electrode, an insulating film disposed on the common electrode, a pixel electrode connected with the switching element and opposed to the common electrode with the insulating film interposed therebetween, and a first alignment film covering the pixel electrode. The second substrate includes a second alignment film. And the pixel electrode includes one main pixel electrode extending in a belt shape in a pixel area defined by the first line and the second line.

Abstract: According to one embodiment, a display device comprises image signal lines, scanning signal lines, pixels, a display area, pixel electrodes, and common electrodes. The common electrodes are configured to detect an object and to display an image in the display area. The common electrodes include first and second common electrodes which are arranged in a first direction. A first slit is provided between the first and second common electrodes. The first and second common electrodes are supplied a signal different from each other. A second slit is provided in the first common electrode. Each of the first slit and the second slit overlaps one of the image signal lines and extends in an extension direction in which the image signal line extends.
