US Patent 7439088 Liquid crystal display device and fabricating method thereof

An array substrate for a liquid crystal display device includes a substrate, a gate line and a data line crossing each other to define a pixel region, a thin film transistor at a crossing of the gate and data lines, a metal pattern over the gate line, a passivation layer exposing the substrate in the pixel region, a part of the thin film transistor and a part of the metal pattern, and a pixel electrode in the pixel region. The pixel electrode is connected to the part of the thin film transistor and contacts the part of the metal pattern. The metal pattern has at least one curved portion in a side contacting the pixel electrode.
