TFT PANEL AND A REPAIRING METHOD OF AN LCD INCLUDING THE SAME CAPABLE OF REPAIRING EASILY A WHITE DEFECT

摘要

PURPOSE: A TFT(Thin Film Transistor) panel and a repairing method of an LCD(Liquid Crystal Display) including the same are provided to repair easily a white defect in a dependent wiring type having an independent storage capacitance wire. CONSTITUTION: A gate line(121) is formed on an insulation substrate(110) and has a gate line(123). A storage electrode wiring has a storage electrode line(131) formed on an upper portion of the substrate and separated from the gate line and a storage electrode(133) connected to the storage electrode line. A gate insulation film(140) covers the gate line and the storage capacitance wiring. A semiconductor layer(151) is formed on an upper portion of the gate insulation film of the gate electrode. A data line(171) has a source electrode crossed with the gate line and a portion of the source electrode is contacted with the semiconductor layer. A drain electrode(175) is positioned oppositely to the source electrode at the center of the gate electrode and overlapped with the storage electrode by interposing the gate insulation film. Red, green and blue color filters(230R,230G,230B) are formed on upper portions of the data line and the drain electrode, sequentially formed at a pixel region surrounded by the gate line and the data line and have an opening portion for exposing the drain electrode. A passivation film(180) covers the color filters and has contact holes(183,182) for exposing the drain electrode together with the opening portion. A pixel electrode(190) is formed on an upper portion of the passivation film and communicated with the drain electrode through the contact hole.
