Patent ID: 7714974

Claim:
A liquid crystal display device, comprising: a common electrode on an upper substrate; a gate driver on a lower substrate facing an upper substrate; an insulating pattern on the common electrode; and a conductive sealant for bonding the upper and lower substrates together that overlaps the gate driver, wherein the gate driver includes: at least one signal line group on the lower substrate to supply power signals and gate control signals; and a plurality of thin film transistors connected to the at least one signal line group, a gate insulating film covering the at least one signal line group; an additional connection pattern on the gate insulating film; a passivation film covering the gate insulating film and the thin film transistor; a first contact hole penetrating the gate insulating film and the passivation film to expose the at least one signal line group; a second contact hole penetrating the passivation film to expose the thin film transistor; third and fourth contact holes penetrating the passivation film to expose the additional connection pattern; a first connection pattern on the passivation film for connecting the at least one signal line group to the additional connection pattern through the first contact hole and the third contact hole; and a second connection pattern formed on the passivation film for connecting the thin film transistor to the additional connection pattern through the second contact hole and the fourth contact hole.
