Abstract
A capacitive touch panel structure with high optical uniformity includes a substrate, a metal layer, an insulating layer and an electrode layer. The metal layer is formed on surface of the substrate to constitute a plurality of metal bridge patterns and a plurality of traces. The insulating layer is coated on the surfaces of the substrate, and a plurality of via holes are formed on partial surface of the metal bridge patterns. A first direction electrode pattern, without electrically connected with the metal bridge patterns, is formed on the surface of the insulating layer between the metal bridge patterns. A second direction electrode pattern covers over the partial metal bridge patterns and into the via holes.
