Abstract
A method for manufacturing a touch screen which includes: providing a substrate including a display area and a non-display area located around the display area; forming a first transparent conductive layer on a side of the substrate, and forming a metal layer on a surface of the first transparent conductive layer facing away from the substrate; forming a first photoresist pattern on the metal layer, at least a portion of the first photoresist pattern corresponding to a metal trace to be formed in the non-display area; performing an etching process by using the first photoresist pattern to form the metal trace; forming a second photoresist pattern only in one of the display area and the non-display area, and performing an etching process to form a first transparent conductive pattern in the display area.
