Abstract
A touch panel includes a substrate, a plurality of peripheral traces, a plurality of marks, a touch sensing electrode, a plurality of first intermediate layers, and a plurality of second intermediate layers. The peripheral traces and the marks are disposed in a peripheral area of the substrate. The first intermediate layers are disposed between the peripheral traces and the substrate, and the second intermediate layers are disposed between the marks and the substrate. Each of the first intermediate layers and the second intermediate layers includes a metal nanowire, and the touch sensing electrode is electrically connected with the peripheral traces. A touch sensor tape is also proposed.
