发明名称 Detection device and electronic apparatus having plural scanning lines, detection lines, power supply lines and plural unit circuits arranged on a substrate
摘要 A unit circuit includes a first transistor, a detection element, a second transistor, and a first capacitive element. The first transistor supplies a detection line with a detection signal corresponding to the electric potential of a gate electrode thereof. The detection element is connected to the gate electrode of the first transistor and varies the electric potential of the gate electrode of the first transistor in accordance with an external factor. The second transistor has a first terminal that is connected to the gate electrode of the first transistor and a second terminal that is connected to a second power supply line. The second transistor has a gate electrode that is connected to a scanning line. The first capacitive element holds the electric potential of the gate electrode of the first transistor.
