Sensor-equipped display device and sensor device

A sensor-equipped display device, comprising:

• first electrodes disposed in a display area, arranged in a first direction and spaced apart from each other, and elongating in a second direction intersecting the first direction;
• a second electrode disposed on an edge portion of the display area, elongating in the second direction, and being adjacent to and spaced apart from the first electrodes on edges located on outermost sides;
• a detection electrode comprising a body portion opposed to the first electrodes, and an expanded portion which is opposed to the second electrode, the detection electrode connected to the body portion and being wider than the body portion;
• and
• a controller urging the first electrodes to function as sensor drive electrodes by supplying sensor drive signals to the first electrodes separately and sequentially, or urging the first electrodes bundled adjacent to each other to function as sensor drive electrodes by simultaneously supplying sensor drive signals to the adjacent first electrodes, and maintaining an electric potential of the second electrode at a value different from electric potentials of the sensor drive electrodes in a sensing period for performing sensing using the detection electrode.

• the first electrodes constituting sensor drive electrodes by being supplied with sensor drive signals separately and sequentially or sensor drive electrodes formed of bundled first electrodes adjacent to each other being constituted by simultaneously supplying the sensor drive signals to the first electrodes adjacent to each other,
• in the sensor drive electrodes constituted in accordance with supply of the sensor drive signals, a width of the sensor drive electrode including the first electrode on the edge being smaller than a width of the other sensor drive electrode not including the first electrode on the edge.
