Patent ID: 8502932

Claim:
A liquid crystal display device comprising: a gate line and a gate electrode formed on a substrate; a common line formed in the same layer as the gate line; a gate insulation film entirely formed on the substrate with the gate line; a data line formed on the gate insulation film opposite to the common line and configured to cross with the gate line and to define a pixel region; a source electrode formed to protrude from the data line; a drain electrode separated by a first distance from the source electrode; a passivation film entirely formed on the substrate with the data line; and a pixel electrode formed on the passivation film and connected to the drain electrode, wherein the common line includes a first and a second common lines separated by a second distance from each other, and a third common line formed within the second distance between the first and the second common lines and used as a repair pattern during a repairing process, wherein the first common line is formed in a lengthwise direction of the data line, wherein the second common line is formed in a lengthwise direction of the gate line, wherein the first common line is formed under and extends along the data line to screen a plurality of light leakage domains, and wherein the third common line is formed in a bar shape, which is configured to cross with the data line, and connected to the first and second common lines.
