ABSTRACT:
A liquid crystal display device comprising a layer of a ferroelectric liquid crystal material sandwiched between opposed first and second electrodes. The display device further comprises a dielectric layer as a capacitative element which is electrically connected through an electrically conductive connecting means to the first electrode so that the dielectric layer and the liquid crystal material are connected in parallel with regard to an external electric source. The display device provides a large area and high information content display, high contrast ratio display, and high gradation display, together with a stabilized memory effect.
