Touch panel and manufacturing method thereof
A touch panel and a manufacturing method thereof are provided. The touch panel includes a substrate, peripheral leads, a touch sensing electrode, and first intermediate layers. The peripheral leads are disposed in a peripheral area of the substrate. The first intermediate layers are disposed between the peripheral leads and the substrate. The touch sensing electrode includes a plurality of modified metal nanowires. The modified metal nanowires have first surfaces in direct contact with each other at an intersection. The modified metal nanowires have second surfaces with covering structures, and the second surfaces are at a non-intersection.
