A liquid crystal display device has a semiconductor integrated circuit capable of outputting a voltage equal to or higher than the source-drain withstand voltage of a component transistor. A switching circuit has first conducting-type first and second transistors connected in series between a first input terminal and a common output terminal and second conducting-type third and fourth transistors connected between a second input terminal and the common output terminal and a switching control circuit for controlling the switching circuit. The switching control circuit applies first and second bias voltages for turning on the second and fourth transistors to the gate electrodes of the second and fourth transistors, and applies a control voltage for selectively turning on/off the first or third transistor to the gate electrodes of the first and third transistors.

The present invention discloses a tape binding device winding a tape piece having an adhesive surface on one side around an electric wire bundle to bundle it. In the device, a pair of arms having a holding surface are lowered while holding the tape piece cut into a predetermined length on the holding surface. As it is lowered, free ends of both arms are lowered to both sides separated by a top portion of the electric wire bundle. At the time of lowering, after winding the tape piece by pressing it around a surface of the electric wire bundle, the free ends of both arms make adhesive surfaces of both ends of the tape piece under the electric wire bundle to adhere each other and are clipped between them, thereby laminating adhesive surfaces each other.
