Abstract:
1. A method of fabricating a liquid crystal display device, the method comprising: sequentially forming a data bus line, an interlayer insulating layer, a semiconductor layer, a gate insulating layer, and a gate electrode on a first surface of a substrate; forming a passivation layer on the substrate; forming a photoresist film on the passivation layer; forming a photoresist pattern from the photoresist film to expose portions of the passivation layer; etching the passivation layer to form a plurality of first contact holes exposing portions of the semiconductor layer and etching the passivation layer, the gate insulating layer and the interlayer insulating layer to form a second contact hole exposing a portion of the data bus line, the first and second contact holes exposing the lower surface of the photoresist pattern; depositing a first portion of a metal film on the photoresist pattern and a plurality of second portions of the metal film within each of the first and second contact holes; removing the photoresist pattern and the first portion of the first metal film to leave the second portions of the first metal film within each of the first and second contact holes; forming a transparent electrode material on the passivation film; and patterning the transparent electrode material to form a pixel electrode within a first one of the plurality of first contact holes, and to form a source electrode having a first portion formed within a second one of the plurality of first contact holes and a second portion formed within the second contact hole wherein the metal film contacts the data bus line and the semiconductor layer through at least one of the contact holes.
