ABSTRACT:
In a common potential stabilizing active matrix liquid crystal display device, the common potential is detected via a common potential detecting terminal provided at the perimeter of the common electrode, the detected potential is compared with a reference potential and the difference is amplified by an amplifier and is negatively fed back to a common potential supply terminal provided at the perimeter of the common electrode.
