Patent ID: 8125603

Claim:
An in-plane switching mode liquid crystal display device (LCD) formed of a plurality of pixels arranged in a matrix, comprising: a gate line formed on a lower substrate; a data line formed such that the data line intersect the gate line to define a pixel region; a Thin Film Transistor (TFT) formed at the intersection of the gate line and the data line; a pixel electrode connected to the TFT; a common electrode to generate a horizontal electric field with the pixel electrode; and a common line supplying common voltage to the common electrode, wherein the common line comprises a first common line formed parallel to the gate line in a lower portion of the pixel region, a second common line formed parallel to the date line in a side portion of the pixel region adjacent to the data line, and a third common line formed parallel to the gate line in a upper portion of the pixel region, wherein the data line comprises a pair of sub-lines facing directly with each other in every two pixel regions, wherein the common electrode comprises a first common electrode connected to the common line and a second common electrode elongated to the pixel region from the first common electrode as well as parallel to the pixel electrode, and wherein the first common electrode is connected to the second common line through a contact hole formed to expose the second common line.
