Patent ID: 7858412

Claim:
A method of fabricating a TFT substrate, the method comprising: disposing gate wiring, which comprises a gate line and a gate electrode on an insulating substrate; disposing a semiconductor pattern and data wiring, which comprises a data line, a source electrode, and a drain electrode on the gate electrode; disposing a passivation layer on the data wiring; disposing a photosensitive film pattern on the passivation layer; etching the passivation layer, which is exposed by the photosensitive film pattern, to form a resultant structure; disposing a conductive layer on substantially an entire surface of the resultant structure; heating the photosensitive film pattern at a temperature sufficient to reflow the photosensitive film pattern; and removing the photosensitive film pattern and the conductive layer disposed on the photosensitive film pattern to form a pixel electrode in a pixel region, wherein the photosensitive film pattern comprises a first region which covers the source electrode and the drain electrode, and a second region which covers the pixel region and has a thickness which is less than a thickness of the first region.
