Abstract
A touch panel includes a substrate, a first sensing electrode layer, and a second sensing electrode layer. The first sensing electrode layer is disposed on the substrate and includes a plurality of first-axis conductive units separated from each other. The second sensing electrode layer is disposed on the substrate and includes a plurality of second-axis conductive units separated from each other and crossing the first-axis conductive units. Each of the second-axis conductive units includes two first conductive layers and a second conductive layer laminated between the first conductive layers.
