    摘要： A common electrode 43 for 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 44) of the pair of electrodes is newly formed. An existing common drive signal Vcom 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 43 and the detection-electrode-for-the-sensor 44, 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 44, and it is unnecessary to newly prepare a drive signal for the touch sensor. Therefore, the configuration is simple.

    摘要： A display unit with touch detection function includes a plurality of pixel signal lines each transmitting a pixel signal for display; a pixel signal line drive section applying the pixel signal to each of the pixel signal lines; display elements each performing display based on the pixel signal; touch detection electrodes each outputting a detection signal based on a change in capacitance occurring due to an external proximity object; and a touch detection section detecting, in a touch detection period, a touch event based on the detection signal, the touch detection period being different from a display period for the display elements to perform display operation. The pixel signal line drive section maintains a voltage of each of the pixel signal lines at a certain level during the touch detection period.
