An electro-optical device includes a pair of substrates that are disposed to face each other with a predetermined gap therebetween, one substrate of the pair of substrates extending from the other substrate on at least one side in plan view, display electrodes that are provided on one substrate, a circuit unit that is provided on one substrate so as to drive the display electrodes, a plurality of lead wiring lines that are led from one of the sides of wiring lines for driving the circuit unit or the display electrodes to an extending portion extending on the one side of one substrate, and a plurality of external connecting terminals that are correspondingly connected to the plurality of lead wiring lines and are provided on a surface of the extending portion facing the other substrate so as to at least partially overlap the plurality of lead wiring lines in plan view.
