1. A method of fabricating a liquid crystal display comprising:

  • a substrate having a main surface, metal gate lines formed on the main surface of said substrate, data lines formed so as to intersect the gate lines, with respect to a plan view of the substrate main surface, at substantially right angles, thin-film transistors formed-near the intersections of the gate lines and the data lines, and pixel electrodes connected to the thin-film transistors to drive a liquid crystal material;

    comprising the steps of;

    anodizing upper and end side surfaces of the gate lines formed on the main surface of said substrate, respectively; and

    continuously patterning insulating films and semiconductor layers stacked thereon, respectively, in a manner such that, with respect to a plan view of the substrate main surface, the patterns effected for each stacked pair of an insulating film and a semiconductor layer are substantially the same and coincide, each such stacked pair covering at least part of the anodized oxide film on respective ones of said gate lines.
