US Patent 7288726 Hollow wire and method for making the same

A hollow wire for enhancing the wires used in a Liquid Crystal Display includes hollow portions so as to increase the cross sectional area and reduce the resistance. An isolation layer with a low dielectric constant is filled in the hollow portions so as to reduce the clecti-ic capacities and maintain the operation efficiency. The isolation layer can be filled in the perpendicularly crossing area between the information lines and gate matrixes to reduce the electric capacities and maintain the operation efficiency. A method for making the hollow wire is also disclosed.
