Abstract: An electronic device includes a sensor configured to sense a touch event in association with the electronic device or a deformation in a physical shape of the electronic device. The sensor includes a first sensor electrode, a second sensor electrode, and a third sensor electrode. The first sensor electrode extends in a first direction. The second sensor electrode extends in a second direction different from the first direction. The second sensor electrode overlaps with the first sensor electrode in a third direction perpendicular to the first direction and the second direction. The third sensor electrode extends in a fourth direction different from the second direction. The third sensor electrode overlaps with the second sensor electrode in the third direction. The first sensor electrode, the second sensor electrode, and the third sensor electrode are insulated from one another and are disposed on different layers than one another.
