Abstract:
1. A method of fabricating an array substrate for a liquid crystal display device, the method comprising: forming a data line, a source electrode, and a drain electrode on a substrate that has a pixel region by depositing and patterning a data metal layer, wherein the source electrode extends from the data line and is separated from the drain electrode; depositing a transparent conductive metal layer on the substrate, wherein the transparent conductive metal layer contacts the drain electrode; patterning the transparent conductive metal layer to form a pixel electrode in the pixel region that contacts the drain electrode; forming an organic semiconductor layer, a gate insulating layer, and a gate electrode of a first metallic material on the substrate, wherein the organic semiconductor layer, the gate insulating layer, and the gate electrode have a substantially same shape; forming a first passivation layer of a photosensitive organic insulating material that has a gate contact hole on the gate electrode, wherein the gate contact hole exposes the gate electrode; and forming a gate line of a second metallic material on the first passivation layer, wherein the gate line contacts the gate electrode through the gate contact hole and crosses the data line to define the pixel region, wherein the pixel electrode lies below the first passivation layer.
