Abstract

A liquid crystal display device having first and second substrates with a liquid crystal layer therebetween, a plurality of gate signal lines and a plurality of drain signal lines, a plurality of pixel regions defined by neighboring gate signal lines and drain signal lines, and a pixel electrode in each pixel region. The drain signal line has a metal layer and another layer formed by a transparent conductor, and the another layer is electrically connected to the metal layer. The pixel electrode is made of a transparent conductor, and a transparent conductor of the pixel electrode and the transparent conductor of the drain signal line are of the same material.
