Claim:
1. A forming method of an electrode pattern of a touch panel, comprising: forming a plurality of electrode pattern cells on a substrate; forming a dielectric layer on the electrode pattern cells; and forming a bridge electrode connecting the electrode pattern cells on the dielectric layer using a conductive material of a black color; wherein the bridge electrode is formed with a metal oxide, metal nitride, or metal fluoride as a blackened metal material; wherein the metal material is one of Al, Au, Ag, Sn, Cr, Ni, Ti, and Mg; wherein the bridge electrode is formed as a plurality of layers formed by using a plurality of conductive materials; wherein among the plurality of layers of the bridge electrode, a lower layer is formed with a conductive material of a first black color and an upper layer is formed with a conductive material of a second black color; and wherein a width of the lower layer corresponds to a width of the upper layer.
