Buffer circuit, scanning circuit, display device, and electronic equipment

A display device comprising:

• a pixel array section including a plurality of pixels respectively including an electro-optic element;
• and
• a scanning circuit that scans the plurality of pixels and has a buffer circuit in an output stage,
• wherein the buffer circuit includes a first transistor circuit and a second transistor circuit,
• wherein the first and second transistor circuits are serially connected between a first fixed power supply and a second fixed power supply, and input terminals and output terminals of each of the first and second transistor circuits are connected in common respectively,
• wherein at least one transistor circuit of the first transistor circuit and the second transistor circuit is a double gate transistor, and
• wherein a switch element, when any one transistor circuit of the first and the second transistor circuits is in an operating state, is comprised to supply a voltage of a third fixed power supply to a common connection node of the double gate transistor of the other transistor circuit.
