ABSTRACT:
The present invention provides a method of manufacturing a TFT array panel in a cost-effective manner. The method includes: forming thin film transistors each having a gate electrode, a source electrode, and a drain electrode; forming an insulating layer on the thin film transistors; forming a first conductive layer electrically connected to the drain electrodes on the insulating layer; forming a second conductive layer on the first conductive layer; forming a photoresist layer including first portions and second portions thinner than the first portions; selectively etching the second conductive layer with a first etchant by using the photoresist layer as an etch blocker; and selectively etching the first conductive layer with a second etchant by using the photoresist layer and the second conductive layer as etch blockers.
