ABSTRACT:
A method of manufacturing an LCD device which includes a gate line having an effective display area which includes an aluminum alloy layer and an aluminum oxide layer. The gate line also includes a gate terminal portion which is made up of the same aluminum alloy layer with a molybdenum alloy layer formed thereon. To form this structure, an insulating substrate of the LCD device, with the laminated structure of the aluminum alloy layer and the molybdenum layer, is immersed in an electrolytic solution. During the immersion, the molybdenum layer is etched off the aluminum alloy in the effective displaying area, while the etching is prevented in the gate terminal area by a protective layer. Following this, the aluminum oxide layer is formed over the aluminum alloy in the effected display area while the device is still immersed in the electrolytic solution.
