1. A method of manufacturing a thin film transistor array panel, the method comprising:
forming a thin film transistor having a gate electrode, a source electrode, and a drain electrode on a substrate;
forming a passivation layer on the source electrode and the drain electrode;
forming a photoresist film on the passivation layer;
selectively etching the passivation layer using the photoresist film as a mask;
forming a conductive film on the remaining portion of the photoresist film and a portion of the gate and the drain electrode; and
removing the photoresist film and the conductive film using a chemical mechanical polishing process to form a pixel electrode connected to the drain electrode.
