ABSTRACT:
An improved method for manufacturing a liquid crystal display unit substantially free from gate electrode breakage but with no increase in the number of manufacturing steps over the conventional method. The liquid crystal display unit includes 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 the gate electrode lines, nonlinear active elements disposed at the intersections of the electrode lines, a confronting electrode substrate having a transparent conductive film on the surface thereof confronting the TFT array substrate, and a liquid crystal display material being held between the confronting electrode substrate and the TFT array substrate. Each of the gate electrode lines is constructed in the form of two layers. One of the two layers is made of display electrode material simultaneously with the formation of the display electrode.
