摘要

PROBLEM TO BE SOLVED: To provide an optically active compound that has high helical induction power, and attains a necessary helical pitch length without largely impairing physical properties and optical properties of a liquid crystal composition by addition to the liquid crystal composition.;SOLUTION: The polymerizable optically active imide compound is represented by general formula (I). The compound wherein both X³ and X⁴ are -CO- in the general formula (I); the compound wherein both ring A² and ring A³ are each a naphthalene ring; the compound wherein ring A¹, A², A³ and A⁴ are all benzene rings; the compound wherein both M¹ and M² are each a hydrogen atom; and the compound wherein ring A¹ and ring A⁴ and ring A² and ring A³ are each the same ring, M¹ and M², X¹ and X⁶, X² and X⁵ and X³ and X⁶ are each the same group and n and m are each the same number, are preferable as the polymerizable optically active imide compound.;COPYRIGHT: (C)2010,JPO&INPIT
