Abstract
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.
Claims9
A scanner comprising a plurality of unit circuits, wherein
- a unit circuit includes a first transistor having a drain electrode to which a signal is input, a source electrode coupled to a scan line, and a gate electrode coupled to a bootstrap node,
- a capacitor coupled between the bootstrap node and the source electrode of the first transistor,
- a second transistor having a source electrode to which a second power supply potential is input, a drain electrode coupled to the scan line, and a gate electrode to which another signal whose phase is reverse of the signal input to the drain electrode of the first transistor is input, and
- a third transistor having a source electrode coupled to the bootstrap node, and a gate electrode to which a first power supply potential is input.
