A driver circuit for a liquid crystal display device has an output terminal, an N-MOS transistor, a P-MOS transistor, a first semiconductor switch connected between the output terminal and the N-MOS transistor and, a second semiconductor switch connected between the output terminal and the P-MOS transistor. Each of the N-MOS transistor and the P-MOS transistor have source, drain, gate and substrate, and form a power source portion taking the source as an output side. The first and second semiconductor switches have control inputting means for inputting a switching control signal for alternately outputting the output voltages of the N-MOS transistor and the P-MOS transistor through the output terminal. The drain, gate and substrate voltages are set so that the output voltage output from the N-MOS transistor is greater than the output voltage output from said P-MOS transistor.
