Abstract:
1. A liquid crystal display device comprising: a first substrate; a liquid crystal display panel formed on one surface of said first substrate, said liquid crystal display panel including a second substrate over said one surface of said first substrate and a liquid crystal layer between said first and second substrates; a semiconductor chip for controlling said liquid crystal display panel, disposed on said first substrate, said semiconductor chip including a wafer substrate on which is formed an integrated circuit, a plurality of external terminals and a first conductive layer, said first conductive layer being not electrically connected in said semiconductor chip to said integrated circuit, said plurality of external terminals including a plurality of signal terminals, a plurality of first fixed potential terminals, a plurality of second fixed potential terminals, and terminals which are electrically connected to said first conductive layer at respective end portions thereof and which are exposed from one surface of said semiconductor chip; and a plurality of second conductive layers formed on said one surface of said first substrate, said plurality of second conductive layers electrically connecting between said plurality of external terminals of said semiconductor chip and an external device, wherein said semiconductor chip is mounted on said first substrate such that said one surface of said semiconductor chip is faced to said one surface of said first substrate and said plurality of external terminals of said semiconductor chip are electrically connected to the corresponding second conductive layers via bump electrodes; wherein first ones of said first fixed potential terminals are electrically connected to one of said terminals which is connected to said first conductive layer, by a first one of said plurality of second conductive layers, and wherein second ones of said first fixed potential terminals are electrically connected to the other of said terminals which is connected to said first conductive layer, by a second one of said plurality of second conductive layers, whereby said first and second ones of said first fixed potential terminals are electrically connected to each other through said first conductive layer of said semiconductor chip.
