Abstract
An output circuit includes a first switch that outputs a positive voltage signal received via a first node when in an ON state, a second switch that outputs a negative voltage signal received via a second node when in an ON state, third and fourth switches that set the first and second nodes to a reference power supply voltage when in an ON state, a first follower circuit that generates, as a gate voltage, a voltage signal following and being in phase with a voltage signal of the first node through source follower operation and supplies the gate voltage to a gate of the first switch, and a second follower circuit that generates, as a gate voltage, a voltage signal following and being in phase with a voltage signal of the second node through source follower operation and supplies the gate voltage to a gate of the second switch.
