Abstract
A touch panel and a manufacturing method thereof are provided. The touch panel has a touch region and a trace region and includes a substrate, a touch device, a shielding trace, and a plurality of conductive traces. The touch device is disposed on the substrate in the touch region and includes a plurality of electrode pads. The shielding trace and the conductive traces are disposed on the substrate in the trace region. At least a part of the conductive traces is electrically connected to the touch device. The shielding trace includes a first trace layer and a second trace layer electrically connected to each other. The shielding trace is disposed between two of the conductive traces, the first trace layer at least partially overlaps the second trace layer, and the shielding trace doesn't overlap the conductive traces.
