Abstract
A hollow wire for enhancing the wires used in Liquid Crystal Display and a method for making the hollow wire which includes hollow portions in the wires so as to increase the cross sectional area and reduce the resistance. Isolation layer with low dielectric constant is filled in the hollow portions so as to reduce the electric 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.
