ANTIFERROELECTRIC LIQUID CRYSTAL COMPOSITE MATERIAL AND ITS PRODUCTION AND LIQUID CRYSTAL ELEMENT FORMED BY USING THIS ANTIFERROELECTRIC LIQUID CRYSTAL COMPOSITE MATERIAL

摘要

PURPOSE:To provide the liquid crystal element which is inexpensive, is fast in electrooptical response, does not generate a switching defect and can make a display screen larger by allowing the org. polymers and antiferroelectric liquid crystal materials in the antiferroelectric liquid crystal composite material to exist in the state of dispersing in each other. CONSTITUTION:This antiferroelectric liquid crystal composite material consists of the org. polymers and the antiferroelectric liquid crystal materials and has these org. polymer and antiferroelectric liquid crystal materials in the dispersed state. The liquid crystal element 10 formed by using such antiferroelectric liquid crystal composite material is composed of a pair of electrodes 20, 20 and the antiferroelectric liquid crystal composite material 1 packed between the electrodes 20 and 20. Plural insulating spherical particles 30 having approximately the same diameter are dispersed into this antiferroelectric liquid crystal composite material 1 and the distance between the electrodes 20 and 20 is maintained constant by these insulating spherical particles 30. At least either of a pair of the electrodes 20 and 20 are formed as transparent electrodes so that the electrooptical change of the antiferroelectric liquid crystal composite material can be observed.
