Abstract
A gate line extending in a horizontal direction is formed on an insulating substrate, and a data line is formed perpendicular to the gate line defining a pixel of a matrix array. Pixel electrodes receiving image signals through the data line are formed in a pixel, and a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode is formed on the portion where the gate lines and the data lines intersect. A storage wire including a storage electrode line in the horizontal direction, a storage electrode connected to the storage electrode line, and at least one of the storage electrode connection portions connecting storage electrodes of neighboring pixels is formed in the same direction as the gate line. A redundant repair line overlaps and is insulated from the storage wire at one end and overlaps the storage wire or the gate wire of a neighboring pixel at the other end is formed in the same layer as the data wire. Also, a storage wire connection portion connecting the storage wires of a neighboring pixel is formed in the same layer as the pixel electrode. In this structure, if portions of the gate wire or the data wire are disconnected, the portions overlapping the disconnected wire, the storage wire, and the redundant repair line are shorted to repair an open wire defect.

Gate lines and a gate shorting bar connected to the gate lines, which include lower and upper films, are formed on a substrate. A gate insulating layer, semiconductors, and ohmic contacts are formed in sequence. Data lines and a data shorting bar connected to the data lines, which include lower and upper films, are formed thereon. A passivation layer is formed on the data lines and the data shorting bar. The passivation layer and the gate insulating are patterned to form contact holes exposing the lower films of the gate lines and the data lines. Connecting portions of the gate lines and the data lines for connection with driving circuits are locate opposite the shorting bars with respect to the contact holes.
