    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.

    Abstract: To provide a liquid crystal display device with a touch detection function in which any drive method can be adopted. The liquid crystal display device is provided with: a liquid crystal element arrangement that has a plurality of liquid crystal display elements arranged in a matrix shape; a plurality of scanning lines that are arranged in each row of the liquid crystal element arrangement, and supply scanning signals to a plurality of liquid crystal display elements arranged in a corresponding row; a plurality of signal lines that are arranged in each column of the liquid crystal element arrangement, and supply an image signal to a plurality of liquid crystal display elements arranged in a corresponding column; a plurality of touch detection drive electrodes which are arranged in a column of the liquid crystal element arrangement, and to which a drive signal for detecting a touch is supplied; and a touch control part that specifies a touch detection drive electrode from the a plurality of touch detection drive electrodes. Here, the drive signal is supplied to the touch detection drive electrode specified by the touch control part.
