Abstract

A touch panel includes a plurality of metal connecting units and a plurality of transparent conductive units. The transparent conductive units are correspondingly connected with the metal connecting units, respectively. Each transparent conductive unit has a plurality of transparent conductors. In one of the transparent conducting units, the transparent conductors are arranged in parallel, and every transparent conductor has one end connecting to the same one of the metal connecting units.
