1. A fringe field switching liquid crystal display comprising:

  • a lower substrate;

    a plurality of gate bus lines extending along a selected direction on the lower substrate;

    a plurality of data bus lines disposed on the lower substrate in a manner such that they are crossed with the plurality of gate bus lines, for defining a unit pixel;

    a gate insulating film for insulating the gate bus lines and the data bus lines from each other;

    a thin film transistor located at a place where the gate bus lines and the data bus lines are crossed with each other;

    a pixel electrode formed directly on the gate insulating film, the pixel electrode in contact with the thin film transistor and disposed in a space of the unit pixel;

    a counter electrode overlapped on the pixel electrode and the thin film transistor, the counter electrode cooperating with the pixel electrode for forming a fringe field which actuates all liquid crystal molecules existing on the pixel electrode and the counter electrode; and

    a passivation layer intervened between the pixel electrode and the counter electrode, wherein the pixel electrode and the counter electrode are made from a transparent conductive material and the plurality of gate bus lines are made as a metal film including aluminum.
