Liquid crystal display having repair lines and methods of repairing the same

A method of repairing a defective data line having a disconnect located along a length of the defective data line in a liquid crystal display, the liquid crystal display having a plurality of duplicate gate lines which each include a primary gate line and a secondary gate line connected to the primary gate line, a plurality of data lines which cross the plurality of duplicate gate lines, and a plurality of repair lines which are parallel to the data lines and cross the duplicate gate lines, wherein the disconnect of the defective data line is located between a first secondary gate line and a second secondary gate line, and wherein said method comprises:

• shorting the defective data line to the first secondary gate line at a first crossing point of the defective data line and the first secondary gate line;
• shorting the defective data line to the second secondary gate line at a second crossing point of the defective data line and the second secondary gate line;
• shorting the repair line to the first secondary gate line at a third crossing point of the repair line and the first secondary gate line;
• shorting the repair line to the second secondary gate line at a fourth crossing point of the repair line and the second secondary gate line;
• isolating a portion of the first secondary gate line extending between the first and third crossing points from a remainder of the first secondary gate line;
• and
• isolating a portion of the second secondary gate line extending between the second and fourth crossing points from a remainder of the second secondary gate line.
