    Abstract: According to one embodiment, a display device includes a plurality of first lines, a plurality of second lines, a plurality of switch elements, a plurality of pixel electrodes, a plurality of third lines, a display layer, and a controller. The plurality of first lines extend in a first direction. The plurality of second lines extend in a second direction. The plurality of third lines extend in the second direction. The switch elements are electrically connected to the first lines and the second lines. The pixel electrodes are connected to the switch elements. The display layer performs an optical operation based on an electrical signal applied to the pixel electrodes. The controller includes at least one switch connected between the second lines and the third lines.

    Abstract: A common electrode for a display, which is originally provided in a liquid crystal display element, is also used as one (drive electrode) of a pair of electrodes for a touch sensor, and the other (detection-electrode-for-the-sensor) of the pair of electrodes is newly formed. An existing common drive signal as a drive signal for display is used in common for a drive signal for the touch sensor. A capacitance is formed between the common electrode and the detection-electrode-for-the-sensor, and touch detection is performed by utilizing a change of this capacitance caused by a finger touch of a user. Thus, a display device with a touch sensor is also applicable to a mobile device in which electric potential of the user is inconstant in many cases. The newly-provided electrode is only the detection-electrode-for-the-sensor, and it is unnecessary to newly prepare a drive signal for the touch sensor.
