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.
