Patent ID: 8921726

Claim:
A touch screen, comprising: a substrate; a conductive pattern formed on at least one side of the substrate; and an insulating layer pattern covering the conductive pattern, wherein the touch screen is manufactured by the method comprising the steps of: a) forming a conductive layer on a substrate; b) forming an etching resist pattern on the conductive layer; and c) forming a first conductive pattern having a line width smaller than the line width of the etching resist pattern by over-etching the conductive layer by using the etching resist pattern, wherein in step c), an etching time of the conductive layer is just-etching time to a time more extended by 2,000% than the lust-etching time, wherein the conductive pattern has a line width of 100 micrometer or less, wherein the conductive pattern has a pattern shape formed continuously on an area of 7 inch or more, wherein the insulating layer pattern has a line width larger than the line width of the conductive pattern, and wherein in a cross-section of the line width direction of the conductive pattern, a percentage a/b*100 of a distance “a” from one end of the conductive pattern to the insulating layer pattern and a distance “b” from the other end of the conductive pattern to the insulating layer pattern is in the range of 90 to 110.
