Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A detection device comprising:
a plurality of detection elements arranged in a matrix having a row-column configuration in a detection area;
a plurality of scan lines each coupled to the detection elements arranged in a first direction;
a drive circuit configured to drive the scan lines;
a plurality of output signal lines each coupled to the detection elements arranged in a second direction different from the first direction; and
a detection circuit configured to be supplied with detection signals from the detection elements through the output signal lines, wherein
the scan lines comprise reset control scan lines each configured to supply a reset control signal to apply a reset potential to the detection elements arranged in the first direction, and
the drive circuit comprises:
a first transistor configured to apply a first potential to each of the reset control scan lines;
a second transistor that is coupled in series to the first transistor, and is configured to apply a second potential lower than the first potential to the reset control scan line; and
a third transistor that is coupled in parallel to the second transistor, and is configured to apply the second potential to the reset control scan line.
