Patent ID: 8188479

Claim:
A pixel electrode structure comprising: a transparent substrate; a data line disposed on the transparent substrate; a common line disposed on the transparent substrate; a first array pixel disposed on the transparent substrate, the first array pixel comprising a first thin film transistor having an extending portion, a first pixel electrode, a first gate line, and a portion of the common line disposed at a lateral side of the first gate line; a first via hole disposed on the common line and in contact with the extending portion of the first thin film transistor; a second array pixel disposed on the transparent substrate, the second pixel array comprising a second thin film transistor having an extending portion, a second pixel electrode, a second gate line, and another portion of the common line being disposed at a lateral side of the second gate line; a second via hole disposed on the common line and in contact with the extending portion of the second thin film transistor; a dummy line disposed at a side of the data line; and a third via hole disposed both on the dummy line and on the common line.
