Abstract
PURPOSE:To obtain the titled liquid crystal element having improved low- temperature working characteristics and quick response and applicable to high- speed optical shutter and a high-density large-sized display, by mixing a specific liquid crystal compound to a ferroelectric liquid crystal. CONSTITUTION:The objective liquid crystal element contains a liquid crystal compound of formula I [A1 and A2 are bivalent 6-membered ring; X is bivalent chain group; at least one of R1 and R2 contains asymmetric carbon atom and at least one of R1 and R2 is a group of formula II (Z is halogen; R3 is 1-18C alkyl) and the other is 1-18C alkyl, or acyl, acyloxy, alkoxy, alkoxycarbonyl or alkoxycarbonyloxy having 1-18C alkyl group) in a ferroelectric liquid crystal layer placed between substrate plates provided with a voltage-applying means and an orientation-controlling layer.
