Claim:
1. A method for manufacturing a conductive pattern, comprising the steps of: a) forming a conductive film on a substrate; b) forming an etching resist pattern on the conductive film; and c) forming a conductive pattern having a smaller line width than a width of the etching resist pattern by over-etching the conductive film by using the etching resist pattern; and d) removing the etching resist pattern after the step c), wherein in the step b), a line edge roughness (LER) of the etching resist pattern is controlled by ½ or less of the line width of a conductive pattern to be formed in the step c), wherein the conductive pattern has a thickness of 100 to 300 nm, and wherein the conductive pattern has an opening ratio of 85% to 98%, and satisfies the following Equation 1: wherein a is a surface resistance of a layer formed of a material constituting the conductive pattern in a thickness of t, and A is a surface resistance of the conductive pattern in a thickness of t.
