Patent ID: 7759176

Claim:
A method for manufacturing a thin film transistor array panel for a liquid crystal display, comprising: on an insulating substrate, forming a gate line including a gate electrode and a storage line including a storage electrode; forming a gate insulating layer covering the gate line and the storage line; forming a semiconductor pattern on the gate insulating layer; forming a data line including a source electrode, a conductor pattern and a drain electrode opposite to the of source electrode; forming a color filter formed of a photosensitive material and covering the data line, the conductor pattern and the drain electrode; forming a first contact hole exposing the drain electrode through the color filter; forming a second contact hole exposing the conductor pattern through the color filter; and forming a pixel electrode connected to the drain electrode and the conductor pattern through the first contact hole and the second contact hole respectively, wherein the semiconductor pattern and the data line are patterned in a single photolithography step.
