Abstract:
1. A fabrication method for a bonding pad structure of a display device, comprising the steps of: providing a substrate; forming a first conductive layer overlying the substrate; forming a protection layer overlying the substrate and the first conductive layer; forming a second conductive layer overlying the protection layer; forming an opening structure penetrating the second conductive layer and the protection layer to expose the first conductive layer; and forming a third conductive layer overlying the second conductive layer to contact the sidewall and bottom of the opening structure; wherein, the third conductive layer is electrically connected to the second conductive layer to provide a first electrical-connection path; wherein, the third conductive layer is electrically connected to the first conductive layer to provide a second electrical-connection path; and wherein the third conductive layer is a transparent conductive layer or an ITO layer.
