Classification: CPC G | IPC G

Claim 13:
14. The display device according to claim 1, further comprising:
a second control signal line,
wherein the display portion further includes a monitoring control line provided corresponding to each of the rows of the pixel matrix,
the scanning signal line drive circuit applies a monitoring control signal to the monitoring control line,
each of the plurality of unit circuits further includes
a third output control circuit including a third internal node, a third output terminal configured to output an on level signal for at least a part of the monitoring period for which the monitoring processing is performed, and a third output control transistor including a control terminal connected to the third internal node, a first conduction terminal, and a second conduction terminal connected to the third output terminal, and
a second output circuit control transistor including a control terminal connected to the second control signal line, a first conduction terminal connected to the first internal node, and a second conduction terminal connected to the third internal node,

a potential to be applied to the second control signal line is switched between a third potential for causing the second output circuit control transistor to be in an on state and a fourth potential for causing the second output circuit control transistor to be in an off state, and
the third potential is applied to the second control signal line throughout the monitoring period.
