SCANNER, ELECTRO-OPTICAL PANEL, ELECTRO-OPTICAL DISPLAY DEVICE AND ELECTRONIC APPARATUS

摘要

A scanner includes a plurality of unit circuits configured with transistors of a same conductivity type. In the scanner, the unit circuit constituting the scanner includes an output transistor that selectively outputs, to an output terminal of the unit circuit, a signal given from an outside. A gate electrode of the output transistor is connected to one end of a voltage limiting transistor, and a gate electrode of the voltage limiting transistor is supplied with a first power supply potential.
