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.
