Patent ID: 7646443

Claim:
An array substrate for a liquid crystal display device, comprising: a first source electrode and a first drain electrode on a substrate, wherein the first source electrode and the first drain electrode are separated from each other and formed of a metallic material; a second source electrode and a second drain electrode on the first source electrode and the first drain electrode, respectively, and are formed of a transparent conductive material, wherein the second source electrode covers an upper surface of the first source electrode, and the second drain electrode covers an upper surface of the first drain electrode; a pixel electrode on the substrate and contacting the second drain electrode on the substrate; an organic semiconductor layer on the substrate; a gate insulating layer on the organic semiconductor layer; a gate electrode on the gate insulating layer; a first passivation layer including a gate contact hole on the gate electrode, the gate contact hole exposing the gate electrode; and a gate line on the passivation layer and contacting the gate electrode through the gate contact hole.
