LIQUID CRYSTAL DISPLAY DEVICE AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display device having an active matrix substrate which shows high adhesion property between a mounted electrode and an interlayer insulating film and which hardly causes peeling of the interlayer insulating film. SOLUTION: A signal line electrode is formed by laminating a second signal line electrode 5b consisting of a conductive film on a first signal line electrode 5a consisting of laminated layers of a titanium conductive film and an aluminum conductive film. The second signal line electrode 5b is used as the mounted electrode 6a.
