Claim 11:
12. The detection device according to claim 11, further comprising a signal line selection circuit configured to sequentially select more than one of all the output signal lines in the detection area along the first direction, and electrically couple the selected output signal lines to the detector in a selection period of the read control scan line, wherein
the detector comprises:
a differential amplifier circuit configured to output a potential difference between voltages generated in the detection elements adjacent in the first direction;
a first capacitive element coupled to a non-inverting input terminal of the differential amplifier circuit;
a second capacitive element coupled to an inverting input terminal of the differential amplifier circuit; and
a switch circuit configured to electrically couple the output signal line to the non-inverting input terminal or the inverting input terminal of the differential amplifier circuit by switching between the non-inverting input terminal and the inverting input terminal in synchronization with selective switching of the output signal lines.
