A method of fabricating a liquid crystal display device includes forming an active pattern on a substrate, forming a first insulating layer on the substrate over the active pattern, forming a gate line including a gate electrode and a data line on the substrate, the data line including a plurality of segmented portions electrically disconnected from each other, forming source and drain regions in the active pattern, forming a second insulating layer on the first insulating layer, the gate line, and the data line, simultaneously forming a pair of first contact holes through the first and second insulating layers, a second contact hole through the second insulating layer, and a pair of third contact holes through the second insulating layer, forming a conductive material along an entire surface of the substrate, and patterning the conductive material to form a drain electrode, a first connection line, and a second connection line on the second insulating layer.
