An LCD device includes an insulating substrate; a gate line disposed on the insulating substrate; a first data line disposed perpendicular to the gate line and separated from the gate line; a second data line disposed crossing the gate line on a same line as the first data line; a thin film transistor disposed substantially at a crossing point of the gate line and the second data line; an active layer disposed below the second data line, a source electrode, and a drain electrode of the thin film transistor; a third data line disposed perpendicular to the gate line to define a pixel region to electrically connect the first and second data lines with each other; and a pixel electrode disposal in the pixel region.
