Abstract:
A method of fabricating a liquid crystal display device, said liquid crystal display device including: a first substrate; a second substrate facing said first substrate with a separation therefrom by a gap; a thin-film transistor formed on said first substrate; and a liquid crystal layer confined in said gap, said method comprising the steps of:forming a semiconductor layer on said first substrate;forming an insulation film on said semiconductor layer;forming a metal layer on said insulation film;anode-oxidizing a surface of said metal layer, to form a first anodic oxide film of a barrier-type on said surface;patterning, after said step of forming said first anodic oxide film, said metal layer to form a conductor pattern defined by a pair of edges such that said conductor pattern includes a gate electrode pattern and a bridging pattern, said bridging pattern extending on said first substrate from said gate electrode pattern to another gate electrode pattern;anode-oxidizing, after said step of patterning said metal layer, said conductor pattern to form a second, porous anodic oxide film on each of said edges of said conductor pattern;anode-oxidizing, after said step of forming said second anodic oxide film, said conductor pattern to form a third, barrier-type anodic oxide film in each of said edges, such that said third anodic oxide film is located inside said second anodic oxide film;removing, after said step of forming said third anodic oxide film, said bridging pattern by an etching process such that said gate electrode pattern is isolated from said another gate electrode pattern; andremoving, after said step of removing said bridging pattern, said second anodic oxide film by an etching process.
