In a switch provided in a driver device and connected to a driver, a terminal and a lever is separated from each other (in the separated state) when a predetermined electric potential is not applied to a gate electrode. When a predetermined electric potential is applied to the gate electrode, the lever of the corresponding switch is deformed by electrostatic force between the gate electrode and the lever and comes into contact with the terminal, and thus the terminals are connected with the lever (in the contact state). A plurality of drivers are connected to the terminals of two or more of switches, respectively, and, when a driving potential is outputted from a driver, the driving potential is applied to a surface individual electrode connected to the switch in the contact state.
