FERROELECTRIC LIQUID CRYSTAL ELEMENT WITH MEMORY PROPERTY

摘要

PURPOSE:To provide even a cell having a liquid crystal layer which is >=5mum thick with excellent memory property by using a ferroelectric liquid crystal material which has a >=30 deg. tilt angle. CONSTITUTION:A liquid crystal material has elastic behavior because of interaction among liquid crystal molecules. This interaction is present even in ferroelectric liquid crystal and a restitutive force to spiral structure is prescribed according to whether the interaction is large or small. The ferroelectric liquid crystal which has a large tilt angle varies in interaction, so the memory property becomes easy to appear. Consequently, even an element having a liquid crystal layer which is >=5mum thick has memory property.
