Original Abstract Submitted

According to an aspect, a detection device includes: a first detection circuit including a first photodiode sensitive to first light and a second photodiode sensitive to second light; and a second detection circuit including a third photodiode sensitive to third light. The first photodiode and the second photodiode are coupled in series and in opposite directions to form a first detection element. One end side of the first detection element is coupled to a first signal line via a first transistor. Another end side of the first detection element is configured to be supplied with a first drive signal. A cathode of the third photodiode is coupled to a second signal line via a second transistor. An anode of the third photodiode is configured to be supplied with a second drive signal.
