Abstract: In an active matrix liquid-crystal display device, dummy contact holes are provided between neighboring terminals, so as to prevent a poor connection between the lower metal layer of a terminal and a TAB caused by conductive particles of an ACF remaining on an organic film, and contact holes that make connections between an upper layer transparent electrode of a terminal and a lower metal layer are formed by a plurality of fine via holes, so that sufficient conductive particles of the ACF remain on the upper transparent electrode and a good connection is made to TAB connection lines.
