Abstract:
1. An active matrix type liquid crystal display device in a transverse electric field system comprising: a video signal line for supplying a drive signal to a liquid crystal drive electrode that drives a liquid crystal in a pixel; a scanning line aligned to cross the video signal line, where the video signal line and the scanning line are aligned in a matrix manner; and two common electrodes running in parallel with one another; wherein the pixels are aligned in a matrix manner corresponding to the matrix formed by the video signal line and the scanning line and each pixel includes the two common electrodes and the liquid crystal drive electrode connected to the video signal line; wherein one of the common electrodes is established adjacent to the scanning line and the two common electrodes are separated by a predetermined distance, and either one of the two common electrodes is established in parallel with the liquid crystal drive electrode; and wherein the two common electrodes are electrically separated from one another and respectively provided with different voltages.
