Patent ID: 8053295

Claim:
A method of fabricating a liquid crystal display device, comprising: forming a gate electrode on a first substrate; forming a gate insulating layer on an entire surface of the first substrate; forming a semiconductor layer on the gate insulating layer; forming source/drain electrodes on the semiconductor layer; forming a passivation layer on the source/drain electrodes; and forming a pixel electrode on the passivation layer, wherein at least one of the gate electrode, semiconductor layer, source/drain electrodes, and pixel electrode is formed by etching a conductive layer or semiconductive layer using a Ti masking layer and Ti pattern, the Ti masking layer being formed by depositing a Ti layer on the conductive layer or semiconductive layer, irradiating light to the Ti layer, and etching the expose portion of the Ti layer by the etching speed different between the Ti layer and the exposed Ti layer.
