1. An electro-optical device comprising:
a feed line;
a light-emitting element that emits light corresponding to a current supplied via the feed line;
a control line that supplies a signal;
a capacitor that stores a potential;
a first transistor that has a first gate electrode electrically connected to the capacitor, the first transistor controlling the current corresponding to the potential;
a second transistor that has a second gate electrode electrically connected to the control line, the second transistor interrupting the current corresponding to the signal; and
a first insulating layer that has a first contact hole through which the second gate electrode and the control line are electrically connected, wherein
in plan view, the control line overlaps with the second gate electrode, and the first contact hole overlaps with the second gate electrode.
