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.

Liquid crystal display device

A thin film transistor protection circuit includes a outer short-circuit line formed around a pixel electrode driving thin film transistor on an array substrate, and a discharging thin film transistor having a gate electrode and a current path connected between a wiring line connected to the pixel electrode driving thin film transistor and the outer short-circuit line. The protection circuit further includes a charging circuit for charging the gate electrode of the discharging thin film transistor according to a difference in potential between the conductive and wiring lines.
