Claim 4:
5. The driving circuit according to claim 4, wherein
the level shift circuit has a third mode in which a reference potential of the amplified modulation signal is determined as a third potential between the first potential and the second potential, and
when the level shift circuit enters the third mode from the first mode,
the third gate driver outputs the fifth gate signal for controlling the fifth transistor to be conductive and the sixth gate signal for controlling the sixth transistor to be nonconductive, then outputs the fifth gate signal for controlling the fifth transistor to be nonconductive and the sixth gate signal for controlling the sixth transistor to be conductive, and thereafter outputs the fifth gate signal for controlling the fifth transistor to be conductive and the sixth gate signal for controlling the sixth transistor to be nonconductive.
