摘要： An array substrate for a liquid crystal display device includes a gate electrode, a gate line and a gate pad electrode disposed on a substrate, each of the gate electrode, the gate line and the gate pad electrode having a first metal barrier layer, a first copper alloy layer, and a first out-diffusion film, and the first out-diffusion film completely covering, surrounding and contacting entire surfaces of the first copper alloy layer. The array substrate includes a gate insulation layer disposed on the substrate and covering the gate electrode, the gate line and the gate pad electrode. An active layer and an ohmic contact layer are sequentially formed on the gate insulation layer and over the gate electrode. A data line is formed on the gate insulation layer and perpendicularly crosses the gate line. A source electrode and a drain electrode contact the ohmic contact layer.
