Patent ID: 7867796

Claim:
A method for fabricating a liquid crystal display comprising: providing a substrate with a thin film transistor (TFT) part defined thereon; forming a metallic film for a gate electrode on the substrate; etching the metallic film through a first printing process to form a gate electrode; sequentially forming a gate insulating layer, a semiconductor layer, and a metallic film for source and drain electrodes on the substrate; selectively etching the metallic film for source and drain electrodes, the semiconductor layer and the gate insulating layer through a second printing process to form a gate insulating layer pattern, a preliminary active pattern and a metallic film pattern which are sequentially stacked such that the gate insulating layer pattern is over-etched from the side of the preliminary active pattern; forming an insulating layer on the substrate with the metallic film pattern; etching the insulating layer to expose the metallic film pattern; forming a transparent conductive film on the metallic film pattern and a remaining insulating film; and selectively etching the transparent conductive film, the metallic film pattern, the preliminary active pattern to form an active pattern, a source electrode, a drain electrode, and a pixel electrode connected with the drain electrode.
