Claim:
1. A liquid crystal display device comprising: a first substrate; a second substrate facing the first substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a first gate line and a second gate line disposed on the first substrate and being substantially parallel to each other; a first common voltage line and a second common voltage line being substantially parallel to the first gate line, each of the first and second common voltage line including a plurality of expanded portions; a first data line and a second data line crossing the first and second gate lines and being substantially parallel to each other; a first thin film transistor connected to the first gate line and the first data line; a second thin film transistor connected to the first gate line and the second data line; a third thin film transistor connected to the second gate line and the first data line; a fourth thin film transistor connected to the second gate line and the second data line; a first pixel electrode connected to the first thin film transistor in a first pixel; a second pixel electrode connected to the second thin film transistor in a second pixel; a third pixel electrode connected to the third thin film transistor in a third pixel; a fourth pixel electrode connected to the fourth thin film transistor in a fourth pixel; a common electrode disposed on the first substrate and overlapping the first, second, third and fourth pixel electrodes; and an insulating layer between the first and second common voltage lines, and the common electrode, wherein the insulating layer has a first contact hole overlapping one of the expanded portions of the common voltage lines in the second pixel, and wherein the insulating layer has a second contact hole overlapping another one of the expanded portions of the common voltage lines in the fourth pixel, and wherein the insulating layer does not have contact holes overlapping the expanded portions of the common voltage lines in the first pixel and the third pixel.
