An electro-optical device and an electronic apparatus are provided with reduced wiring resistance. A second wiring pattern for connecting an upper wiring connected to a mounting terminal to a first inter-substrate conducting terminal includes a base electrode. An inorganic insulating film is not attached to the sides of the base electrode. As a result, the upper wiring on each side of the base electrode and the first inter-substrate conducting terminal are electrically connected to the base electrode through the sides. The path from the mounting terminal to the first inter-substrate conducting terminal is formed in the order of upper wiring, one side of the base electrode, base electrode, the other side of the base electrode, and then the first inter-substrate conducting terminal. The second wiring pattern uses the base electrode formed of a metal film to sharply reduce wiring resistance.
