Abstract
A drive circuit includes a first voltage output circuit coupled to a first terminal and outputting a first voltage signal, a second voltage output circuit coupled to a second terminal and outputting a second voltage signal, and a drive signal output circuit coupled to the first terminal and outputting a drive signal. In a first mode, the second voltage output circuit outputs the second voltage signal and the drive signal output circuit outputs the drive signal whose voltage value varies. In a second mode, the second voltage output circuit outputs the second voltage signal and the drive signal output circuit outputs the drive signal which is constant at a third voltage value. In a third mode, the first voltage output circuit outputs the first voltage signal and the second voltage output circuit outputs the second voltage signal.
