Method of fabricating a liquid crystal display with redundant interconnections

摘要

A method of fabricating a thin film transistor liquid crystal display (TFT-LCD) is provided. The TFT-LCD is formed on a substrate having a scan line and a signal line. The scan line and the signal line are perpendicular to each other and located on two different planes. The method includes the following steps: forming a passivation layer covering the thin film transistor and the signal line; patterning the passivation layer to form a signal line contact hole in the passivation layer above the signal line; forming a transparent conductive layer above the signal line and filling into the signal line contact hole; and then patterning the transparent conductive layer for remaining the transparent conductive layer located above a crossing region of the scan line and the signal line.
