1. In a method for manufacturing a liquid crystal display unit comprising:

  • a TFT array substrate including a plurality of gate electrode lines juxtaposed on a transparent insulating substrate, a plurality of source electrode lines arranged across said gate electrode lines, and nonlinear active elements and display electrodes provided at the intersections of said electrode lines;

    a confronting electrode substrate having a transparent conductive film on the surface thereof and confronting said TFT array substrate; and

    a liquid crystal display material held between said confronting electrode substrate and said TFT array substrate, the improvement wherein each of said gate electrode lines is made in the form of two layers, each comprising a different material and one of said two layers being made of display electrode material simultaneously with the formation of said display electrode.
