Patent ID: 7800104

Claim:
An array substrate for a liquid crystal display device, comprising: a data line on a substrate; a source electrode contacting and overlapping the data line, a drain electrode spaced apart from the source electrode and a pixel electrode connected to the drain electrode, wherein the source electrode, the drain electrode and the pixel electrode each include transparent conductive material; a data pad at one end of the data line, wherein the data pad is disposed in a same layer as the data line; a data pad terminal on the data pad, wherein the data pad terminal includes a same material as the source and drain electrodes and the data pad terminal is disposed in a same layer as the source and drain electrodes; an organic semiconductor layer contacting the source and drain electrodes; a gate insulating layer on the organic semiconductor layer; a gate electrode on the gate insulating layer; a first passivation layer on the gate electrode, the first passivation layer having a gate contact hole exposing the gate electrode; and a gate line on the first passivation layer, the gate line connected to the gate electrode through the gate contact hole.
