1. A method of fabricating a liquid crystal display device, comprising the steps of:

  • forming a gate electrode, a gate bus line, and a gate pad on a substrate using a first mask process;

    forming a gate insulating layer and an active layer on an entire surface of the substrate;

    forming a first organic material film on an entire surface of the substrate;

    removing a portion of the first organic material film to expose a first portion of the gate pad;

    depositing a transparent film on an entire surface of the substrate;

    patterning the transparent film using a second half-tone mask to form a data bus line, a source electrode, a drain electrode, a pixel electrode, a channel layer, and an ohmic contact layer;

    exposing portions of the data pad and data bus line using a third mask;

    forming a second organic material film on an entire surface of the substrate;

    depositing a low resistance material on the data bus line;

    coating a passivation film on the substrate;

    removing the second organic material film using a lift-off process to expose a second portion of the gate pad and a first portions of the data pad.
