Abstract
A touch sensor having a visible area and a peripheral area at least on one side of the visible area includes a substrate, a touch electrode layer, and peripheral traces. The touch electrode layer is disposed on a surface of the substrate and includes touch electrodes corresponding to the visible area. The peripheral traces are disposed on the surface of the substrate and corresponding to the peripheral area. The peripheral traces are respectively electrically connected to the touch electrodes. Each of the peripheral traces includes a matrix and metal nanowires distributed in the matrix. A line width of each of the peripheral traces is more than or equal to 6 μm and less than or equal to 12 μm, and a line spacing of any adjacent peripheral traces of the peripheral traces is more than or equal to 6 μm and less than or equal to 12 μm.
