Title: Liquid crystal display element
Inventor: IWANAGA HIRONORI
IPC: G02F1/137
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To suppress production of stripe domain and hysteresis due to excessive twisting force in a liquid crystal bulk and to obtain a bright and sharp image display, by allowing an optically active compd. or a structural body having a helical structure to be locally present on the interface between a substrate surface and a liquid crystal layer. SOLUTION: A chiral highly-coordinated phosphorus compd. 3 adsorbs on the interface between a substrate 1 and a liquid crystal layer 2. When a N-type liquid crystal material or P-type dichroic dye is used, the initial state shows homeotropic orientation and gives a color-erased mode. When voltage is applied on the cell, the liquid crystal layer causes phase transition into a helical structure by the twisting force of the interface to have a colored state. Since the surface of the substrate 1 where the highly coordinated phosphorus compd. 3 adsorbs is made hydrophobic by alkyl substituents for the phosphorus atoms, the surface has a homeotropic orientation in the initial state. When voltage over the threshold is applied, the twisting force becomes dominant to cause phase transition into a helical structure. As for the helical structural body, helical polymers can be cited.
