First and second electrodes and first and second electrical connection portions
are overlapped and electrically connected. A first substrate includes: an attachment
portion, a connection portion and an extension portion, the attachment portion
being attached to the second substrate, the connection portion being connected
to the attachment portion and positioned outside the second substrate, and the
extension portion being extending from the connection portion along an edge of
the second substrate without overlapping the second substrate. The first electrical
connection sections are formed on the extension portion of the first substrate.
