Abstract
A device for attenuating stray capacitances in a liquid crystal and active matrix screen. The screen includes a substrate plate on one face of which there are deposited electrodes and thin film components controlling the electrodes. It also includes a back plate having one or more back-plate electrodes and covering the face of the substrate plate. A liquid crystal is contained between the electrode of the substrate plate and the back-plate electrodes. A ground plane forms an equipotential over the whole surface of the screen between the substrate plate and the thin films of the control components. The ground plane along with a film of insulating material forms a storage capacitance.
