A pixel structure of a transflective LCD panel includes a substrate, a data line and a scan, a thin film transistor containing an extending electrode, a first common electrode and a second common electrode, a transmissive pixel electrode, and a reflective pixel electrode forming a first coupling capacitor with the extending electrode and a second coupling capacitor with the second common electrode. The first and second common electrodes and the data line overlap with each other in an overlapping area, wherein the first common electrode is disposed between the second common electrode and the data line.
