Abstract: A touch panel which is used as an input device for an electronic device, etc., and an electronic device including the touch panel are provided. A touch panel includes a first substrate, and a second substrate spaced from the first substrate by a distance and having a contact surface. A fluid is filled in a gap between the first substrate and the second substrate, and an input button area is delimited due to movement of the fluid when a driving voltage is applied. If a thickness of the gap between the first substrate and the second substrate is reduced below a threshold thickness value in the input button area, the driving voltage is cut off.
