Patent ID: 8879039

Claim:
A liquid crystal display device comprising: a liquid crystal panel including pluralities of bonding portions formed in its one edge, pluralities of gate and data lines arranged on the liquid crystal panel, and pixel regions defined by the gate and data lines, one of the bonding portions including: first metal patterns formed away from each other and on a thin film transistor array substrate of the liquid crystal panel; a gate insulation film and a protective layer sequentially formed to cover the first metal patterns; and a second metal pattern formed on the protective layer and electrically connected to the first metal patterns partially exposed by contact holes which are formed by partially etching the gate insulation film and protective layer, the second metal pattern being_in contact with an entire surface of the first metal patterns exposed by the contact holes, and a portion of the second metal Pattern in contact with the first metal patterns exposed by the contact holes having a flat upper surface, wherein the second metal pattern is electrically connected to a plurality of the first metal patterns through the contact holes, wherein the bonding portions are used as regions to which driver IC chips are attached, and the second metal pattern is electrically connected to a representative driver IC chip which is attached to the thin film transistor array substrate together with other driving circuits, and wherein the bonding portions are arranged only in a top edge of the liquid crystal panel.
