Abstract

The present invention relates to a touch screen and a manufacturing method thereof. The manufacturing method comprises the steps of: a) forming a conductive film on a substrate; b) forming an etching resist pattern on the conductive film; c) over-etching the conductive film using the etching resist pattern to form a conductive pattern whose linear width is smaller than the width of the etching resist pattern. According to the present invention, a touch screen having an ultra-fine linear width conductive pattern is provided in an efficient and economical manner.
