Patent ID: 7489368

Claim:
A method of fabricating a liquid crystal display device, comprising: forming a data line and a pixel electrode on a lower substrate using transparent conductive material, wherein the data line includes a source electrode and the pixel electrode includes a drain electrode; forming a semiconductor layer overlapping portions of the data line and the pixel electrode on the data line and the pixel electrode; forming a gate insulating layer covering the data line, the pixel electrode and the semiconductor layer on the lower substrate; forming a gate line on the gate insulating layer; forming a passivation layer covering the gate line on the gate insulating layer; bonding the lower and upper substrates to each other; and forming a liquid crystal layer between the lower and upper substrates, wherein surfaces of the data line, including the source electrode, and the pixel electrode, including the drain electrode, are treated to have hydrophilic properties and then all the semiconductor layer, the gate insulating layer, the gate electrode and the passivation layer are formed of organic material.
