Abstract
An electronic device includes a plurality of first wiring lines, a plurality of second wiring lines that intersect the plurality of first wiring lines, a plurality of unit circuits that are disposed so as to correspond to intersections between the plurality of first wiring lines and the plurality of second wiring lines, and a plurality of reference signal lines that supply reference signals to the plurality of unit circuits. Each of the plurality of unit circuits has a driven element that is driven by a driving voltage or a driving current, a driving unit that supplies the driving voltage or the driving current to the driven element, a switching element that controls electrical connection between an input terminal provided in the driving unit and one of the plurality of second wiring lines, and a capacitor element that has a first electrode connected to the input terminal and a second electrode connected to one of the plurality of reference signal lines, and accumulates a charge between the first electrode and the second electrode.
