The voltage modifying part is configured to modify the gate-on voltage to a swing-on signal based on the kickback control signal, the swing-on signal including a slicing part, the slicing part including a falling portion during which a level of the swing-on signal falls from the first high level to a second high level lower than the first high level, and a rising portion during which the level of the swing-on signal rises from the second high level to the first high level. The slope control part is configured to decrease a slew rate of the rising portion in the swing-on signal and to output the swing-on signal decreased the slew rate of the rising portion as a gate-on signal.
