  • Publication number: 20080009108
    Abstract: A display panel structure having a circuit element disposed thereon and method of manufacture are provided. The display panel includes a substrate and the circuit element disposed on the substrate. The circuit element has a first interface layer and a first conductive layer. Both the first interface layer and the first conductive layer have copper materials. The material which makes the first interface layer includes a reactant or a compound of the material which makes the first conductive layer. The method for manufacturing includes the following steps: forming a first interface layer on the substrate; forming a first conductive layer on the first interface layer; and etching the first conductive and interface layers to form a pattern. The existence of the first interface reduces the penetration of the first conductive layer on the substrate and improves the adhesive force between the first conductive layer and the substrate.
