Abstract
A pixel electrode structure includes a transparent substrate, a data line, a common line, a first array pixel, and a second array pixel disposed on the transparent substrate. The first/second array pixels respectively include a thin film transistor, a pixel electrode, and a gate line, and the common line is disposed at a lateral side of the gate line. A first via hole and a second via hole are respectively disposed on common line and in contact with an extending portion of the first thin film transistor and an extending portion of the second thin film transistor. A dummy line is disposed at a side of the data line, and a third via hole is disposed both on the dummy line and on the common line. The present invention can not only increase the aperture ratio of the pixel, but have a better stability of the common voltage signal.
