Abstract:
A method for manufacturing a thin film transistor array panel for a liquid crystal display comprising the steps:forming a gate wire on an insulating substrate by using a first photolithography process; forming a layer pattern including a gate insulating layer pattern, a semiconductor layer pattern and an ohmic contact layer pattern on the gate wire by using a second photolithography process, the step of forming the layer pattern including only one photolithography process; forming a conductor pattern having a dual-layered structure including of a lower conductor layer and an upper conductor layer by using a third photolithography process; removing a portion of the ohmic contact layer pattern which is not covered with the conductor pattern; forming a passivation layer by using a fourth photolithography process; and removing a portion of the upper conductor layer of the conductor pattern which is not covered with the passivation layer.
