Abstract
A liquid crystal display device including, a first substrate, a second substrate spaced apart from and facing to the first substrate, and provided with a counter electrode, and a liquid crystal composition layer hermetically filled in between the first substrate and the second substrate, wherein a switching element and a transparent pixel electrode connected to the switching element are formed on the first substrate, and the switching element comprises an active layer formed of either polycrystalline silicon or amorphous silicon, an insulating layer containing silicon which is formed on the active layer and provided with an opening, and a wiring electrically connected via the opening with the active layer and formed the insulating layer. The wiring is formed of an alloy comprising 0.1 to 10 mol % of a metal which is capable of reducing the insulating layer containing silicon and 90 mol % or more of copper.
