When there is an open defect in one of the data lines, the alignment signal is capable of being transmitted to the corresponding data line from the first end and the second end thereof through the transmitting line, which allows the alignment signal to be applied to the corresponding data line except the open defect. This improves the alignment consistence of liquid crystal molecules and reduces the scrap rate of the liquid crystal panel.
