Claim 3:
4. The driving circuit according to claim 1, wherein
the level shift circuit includes a third gate driver that outputs, based on the base driving signal, a fifth gate signal and a sixth gate signal, a fifth transistor that has one end electrically coupled to a third output point and the other end to which a signal based on the amplified modulation signal is supplied and that operates based on the fifth gate signal, a sixth transistor that has one end electrically coupled to the third output point and the other end to which a second power source voltage is supplied and that operates based on the sixth gate signal, and a second capacitance element that has one end to which a signal based on the amplified modulation signal is supplied and the other end electrically coupled to the other end of the sixth transistor, and
the third output point is electrically coupled to the other end of the third transistor and the one end of the first capacitance element.
