An output circuit is provided. The disclosure includes: a positive polarity voltage signal supplying circuit configured to supply or block the supply of a positive polarity voltage signal having a voltage higher than a reference power source voltage to a first node; a negative polarity voltage signal supplying circuit configured to supply or block the supply of a negative polarity voltage signal having a voltage lower than the reference power source voltage to a second node; a first switch formed from a P channel transistor of which a source and a back gate are connected to the first node and a drain is connected to a first output terminal; a second switch formed from an N channel transistor of which a source and a back gate are connected to the second node and a drain is connected to the first output terminal; and third and fourth switches.
