Abstract: An active panel of a liquid crystal display having a thin film transistor and a pixel electrode arranged in a matrix pattern has a double gate us line. On a substrate, a gate bus line, a gate electrode and a gate pad are formed using a first metal such as aluminum having low electrical resistance and a second metal such as chromium having surface stability. Then, a dummy source bus line and a dummy source pad are formed prior to forming a source bus line and a source pad so as to eliminate line disconnection due to the cracks thereof and to thereby reduce the defects of the active panel and the increase production yield of the manufacturing process.
