Patent ID: 7135360

Claim:
A method of fabricating a liquid crystal display device, comprising: forming a gate electrode on a first substrate using a first hydrophilic TiO 2 pattern forming the gate electrode including: forming a metal layer on the first substrate, forming a hydrophobic TiO 2 masking layer on the metal layer, the hydrophobic TiO 2 masking layer having first and second parts, exposing the first part of the hydrophobic TiO 2 masking layer to light to form a hydrophilic TiO 2 layer, forming the first hydrophilic TiO 2 pattern by etching the second part of the hydrophobic TiO 2 masking layer, etching the metal layer using the first hydrophilic TiO 2 pattern as a mask to form the gate electrode and the first hydrophilic TiO 2 pattern on a surface of the gate electrode; forming a gate insulating layer on the first substrate, the first hydrophilic TiO 2 pattern disposed between the gate electrode and the gate insulating layer; forming a semiconductor layer on the gate insulating layer; forming source and drain electrodes on the semiconductor layer; forming a passivation layer on the first substrate; and forming a pixel electrode on the passivation layer.
