Abstract
PURPOSE:To obtain a sharp image of a high contrast by forming a ferroelectric material layer to the capacity smaller than the capacity of a liquid crystal layer. CONSTITUTION:An electrode 13 consisting of ITO is formed on an insulating substrate 12 consisting of a glass substrate and the ferroelectric material layer 14 consisting of a copolymer of vinylidene fluoride and trifluoroethylene is formed on the electrode 12. The liquid crystal layer F is held between a substrate D consisting of an electrode 15 made of Cr and a counter substrate E formed on an electrode 17 made of ITO on an insulating substrate 16 consisting of a glass substrate, on the ferroelectric material layer 14. The relation CLC/CF >1 is satisfied between the capacity CLC of the liquid crystal layer F and the capacity CF of the ferroelectric material layer 14. The erasing of the display data by the leak current of the liquid crystal itself is thereby obviated and the sharp image of the high contrast is obtd.
