Patent ID: 7436480

Claim:
A liquid crystal display device, comprising: an upper substrate where a common electrode is formed; a lower substrate that faces the upper substrate; a plurality of gate drive integrated circuits that supplies a gate signal to a gate line that is located on the lower substrate; a plurality of data drive integrated circuits that supplies a data signal to a data line that is located on the lower substrate; a common line that supplies a common voltage to the common electrode through the gate drive integrated circuit and the data drive integrated circuit when driving a liquid crystal, wherein the common line includes a first common line passing through the gate drive integrated circuits; and a second common line passing through the data drive integrated circuits; a conductive sealant that electrically connects the common electrode to the common line in one of an area between adjacent gate drive integrated circuits and between adjacent data drive integrated circuits; a gate insulating film that covers the first and second common lines; a passivation film formed on the gate insulating film; a first supply contact hole that penetrates the gate insulating film and the passivation film to expose the first common line; a second supply contact hole which penetrates the gate insulating film and the passivation film to expose the second common line; a first conductive pattern that is in contact with the first common line through the first supply contact hole and with the conductive sealant; and a second conductive pattern that is in contact with the second common line through the second supply contact hole and with the conductive sealant.
