Patent ID: 7439088

Claim:
A method of manufacturing a liquid crystal display device, the method comprising: providing first and second substrates; forming a gate line and a data line on a substrate, the gate and data lines crossing each other to define a pixel region; forming a thin film transistor at a crossing the gate and data lines; forming a metal pattern over the gate line; forming a passivation layer exposing the substrate in the pixel region, a part of the thin film transistor and a part of the metal pattern; forming a pixel electrode in the pixel region, the pixel electrode connected to the part of the thin film transistor and contacting the part of the metal pattern; and forming a liquid crystal layer between the first and second substrates, wherein the passivation layer exposes a side surface of the metal pattern, the pixel electrode contacts the side surface of the metal pattern, and the metal pattern has at loast one curved portion in the side surface contacting the pixel electrode, the at least one curved portion having an angle larger then 90 degrees.
