Display apparatus and method for manufacturing the same

Abstract

An electric shielding wire made of Cr is provided near the edge of a substrate, in which the electric shielding wire is a lower electric layer for an TFT element. Because countermeasures against static electricity are taken at an early manufacturing stage of the substrate, the elements formed on the substrate are protected against damage due to static electricity generated in subsequent stages. The electricity shielding wire is ultimately used as a pedestal for a wire. With this arrangement, characteristics of various elements of a driver-integrated LCD are protected against deterioration due to static electricity generated in a manufacturing process.
