An electro-optical device includes first switching elements which are correspondingly provided at intersections of a plurality of scanning lines and a plurality of data lines in a display region, at least three metal layers which are provided in the display region, a wiring line portion which is provided in an adjacent region of the display region and supplies signals to second switching elements through signal lines formed of at least two metal layers of the three metal layers, and an electromagnetic shield which is provided in the adjacent region of the display region. The electromagnetic shield has a first shield portion which covers the wiring line portion using metal layers other than the metal layers forming the signal lines, and a second shield portion which is electrically connected to the first shield portion and is disposed between the signal lines.
