1. A position detection device comprising:
a plurality of sensor electrodes including a first sensor electrode and a second sensor electrode that are adjacent to each other, and a third sensor electrode adjacent to the second sensor electrode with the first sensor electrode intervening therebetween;
a plurality of connection wires each of which is connected to a corresponding one of the plurality of sensor electrodes and which includes a first connection wire connected to the first sensor electrode and a second connection wire connected to the second sensor electrode;
a sensor controller connected to the plurality of connection wires;
a first extension line;
a second extension line; and
a third extension line,
wherein:
some of the plurality of connection wires, including the first connection wire, extend at regular intervals in a first region,
the plurality of connection wires other than the some of the plurality of connection wires, including the second connection wire, extend at regular intervals in a second region different from the first region,
the first extension line extends along the second connection wire in the second region and is electrically connected to the first sensor electrode,
the second extension line extends along the first connection wire in the first region and is electrically connected to the second sensor electrode, and
the third extension line extends along the first extension line in the second region and is electrically connected to the third sensor electrode.
