Location detection device and electronic apparatus

An electronic apparatus comprising:

• a display device;
• and a location detection device, wherein the location detection device includes:
• a sensor arranged to overlap with the display device, and a sensor controller arranged to overlap with the display device, wherein the sensor includes a plurality of detection electrodes arranged side by side in a first direction of a panel surface, wherein the sensor controller, in operation, detects a location of an electromagnetic induction pen, based on a third alternating current generated by using both a first alternating current output from a first detection electrode located proximate one end of the plurality of detection electrodes in the first direction, and a second alternating current output from a second detection electrode located on an opposite side of a center of the panel surface in the first direction from the first detection electrode, and wherein noise derived from a gate line and superposed on the first alternating current of the first detection electrode is canceled by the noise derived from the gate line and superposed on the second alternating current of the second detection electrode.
