Patent ID: 7618554

Claim:
A liquid crystal composition comprising: at least 15% by mass of a compound having a terminal structure represented by general formula (I) below: wherein —O-Q represents is represented by partial structural formula (II) below: —O—CF 2 —CF═CF 2 (II); at least one compound represented by any of general formulae (III-1) to (III3) below (Component A), with the proviso of excluding components included in the compounds having a terminal structure represented by general formula (I): wherein: R 1 represents R 0 , R 0 O, R 0 OCO, or R 0 COO; R 0 represents an alkyl group, containing one or more unsaturated bonds, one or more —CH 2 — groups may be replaced by —O—, —CO—, or —COO—, and part or all of the hydrogen atoms may be replaced by a halogen atom or cyano group; X 1 and X 2 each independently represent a hydrogen or fluorine atom; Q 1 represents a halogen atom, haloalkyl group, haloalkoxy group, haloalkenyl group, or haloalkenyloxy group; and X 5 to X 8 each independently represent a hydrogen or fluorine atom; and at least one compound represented by any of general formulae (IV-1) to (IV-3) below (designated as Component B), with the proviso of excluding components included in the compounds having a terminal structure represented by general formula (I): wherein: R 2 represents R 0 , R 0 O, R 0 OCO, or R 0 COO; R 0 represents an alkyl group, containing one or more unsaturated bonds, one or more —CH 2 — group may be replaced by —O—, —CO—, or —COO—, and part or all of the hydrogen atoms may be replaced by a halogen atom or cyano group; X 3 and X 4 each independently represent a hydrogen or fluorine atom; Q 2 represents a halogen atom, haloalkyl group, haloalkoxy group, haloalkenyl group, or haloalkenyloxy group; and X 9 and X 10 each independently represent a hydrogen or fluorine atom.
