Abstract: A display device includes: a display panel having a front surface and a back surface and displaying an image on the front surface; a plurality of detection electrodes overlapping the display panel when seen in a plan view; and a shield electrode overlapping the display panel when seen in a plan view. The shield electrode is arranged on a side opposite to a side of the front surface with respect to the plurality of detection electrodes. Based on electrostatic capacitance of the shield electrode, proximity or contact of an object to the front surface is detected, and based on electrostatic capacitance of each of the plurality of detection electrodes, a position of the object is detected.

Abstract: A sensing unit performs a first sensing process of sensing an approach or a contact of an object to a display panel by collectively sensing electrostatic capacitance of each of a plurality of sensing electrodes provided in a matrix pattern. Further, in a case where the approach or the contact of the object has not been sensed in the first sensing process, the sensing unit repeats the first sensing process, and in a case where the approach or the contact of the object has been sensed in the first sensing process, the sensing unit performs a second sensing process of sensing a position of the object by individually sensing the electrostatic capacitance of each of the plurality of sensing electrodes.

Abstract: A noise immunity of a detected capacitance is prevented or inhibited from lowering on a driving electrode different in width from the other driving electrodes, provided in an input device. A touch panel serving as an input device has a plurality of driving electrodes extending in an X-axis direction and arranged in a Y-axis direction intersecting with the X-axis direction, and a driving electrode arranged outside one side of an arrangement of the driving electrodes and extending in the X-axis direction. Further, the touch panel TP1 has a plurality of detecting electrodes extending in the Y-axis direction and arranged in the X-axis direction. The width of the driving electrode is smaller than the widths of the driving electrodes and the detecting electrode includes an expanding portion for expanding the area of the detecting electrode on the side opposite to the plurality of driving electrodes via the driving electrode.
