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.

Claim (Index 1):
A display device having a capacitive touch sensor, comprising:\n a first substrate; a second substrate facing the first substrate; a display function layer having an image display function, the display function layer being interposed between the first substrate and the second substrate, the second substrate having (a) a display function layer side facing the display function layer and (b) an upper surface side facing away from the display function layer side; a plurality of display pixel electrodes; a common electrode facing the display pixel electrodes, the display pixel electrodes and the common electrode being disposed between the first substrate and the display function layer; a control circuit that controls display of an image by applying a voltage to the display pixel electrode and the common electrode based on an image signal; a touch detection electrode for the capacitive touch sensor, the touch detection electrode overlapping the common electrode; and a touch detection circuit that detects a position touched by an object based on a detection signal obtained from the touch detection electrode, the touch detection electrode being disposed on the upper surface side of the second substrate.
