Abstract
On a transparent substrate, a photosensitive resin layer, which is made of an acrylic positive photosensitive resin layer, is formed so as to cover stripe-shaped conductive wires and a portion between the conductive wires. In this case, at least a part of the photosensitive resin layer, that covers the conductive wire, is removed. And then, a transparent conductive film is formed on the photosensitive resin layer and the conductive wire, and the transparent conductive film is patterned so as to form transparent electrodes. Such an electrode substrate can obtain high evenness when a height difference is at 0.11 &mgr;m or less between a projecting portion, which appears on the photosensitive resin layer around the ends of the conductive wires after the photosensitive resin layer has been removed so as to expose the conductive wire, and the virtually even surface of the resin film at a portion where the conductive wire is not formed, and a height difference is 0.11 &mgr;m or less between the projecting portion and the surface of the conductive wire. Consequently, it is possible to improve evenness of the electrode substrate in which the conductive wires are formed so as to be conducti…
