Patent ID: 7978292

Claim:
A thin film transistor (TFT) array panel for a liquid crystal display (LCD), comprising: a substrate; a gate line formed on the substrate; a plurality of common electrodes formed on the substrate; a gate insulating layer formed on the gate line; a semiconductor pattern formed on the gate insulating layer; an ohmic contact layer pattern formed on the semiconductor pattern; a data wiring pattern comprising a data line, a source electrode and a drain electrode, the source electrode and the drain electrode being formed on the ohmic contact layer pattern; a plurality of pixel electrodes connected to the drain electrode and arranged parallel to the common electrodes; a redundant data line arranged parallel to the data line and formed on the data line to overlap the data line; and a redundant pad being connected to the gate line or the data line, wherein the common electrodes and the pixel electrodes are formed on the same layer as the gate line.
