Touch screen and manufacturing method thereof
The present invention provides a method of manufacturing a touch screen, 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 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 and a touch screen manufactured by the method. According to the present invention, a touch screen comprising a conductive pattern having an ultrafine line width can be economically and efficiently provided.
