<P>PROBLEM TO BE SOLVED: To prevent large overshoots and undershoots. Ž<P>SOLUTION: The driver circuit includes: (1) a first CMOS circuit and a second CMOS circuit connected in parallel; and (2) a control part for conducting a first P-type FET and a second P-type FET before a driving voltage reaches the first threshold of the control part (2Aa) and conducting only the second P type FET after the driving voltage reaches the first threshold of the control part (2Ab) when an input voltage is switched from a first voltage to a second voltage (2A), and conducting a first N-type FET and a second N-type FET before the driving voltaeg reaches the second threshold of the control part (2Ba) and conducting only the second N-type FET after the driving voltage reaches the second threshold of the control part (2Bb) when the input voltage is switched from the second voltage to the first voltage (2B).
