ABSTRACT:
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.
