| abstract |
The present invention relates to a liquid crystal composition having a negative dielectric constant anisotropy, comprising one or more compounds represented by the general formula (i) and a polymerizable compound represented by the general formula (ii). 1 type or 2 or more types, and the nematic phase-isotropic liquid phase transition temperature is 100 degreeC or more. (R i1 and R i2 represent alkyl groups having 1 to 8 carbon atoms, n i1 represents 1 or 2, P 1 and P 2 represent polymerizable groups of formulae (PG-1) to (PG-5), and S 1 and S 2 represents a single bond or an alkylene group with 1 to 5 carbon atoms, X 1 to X 8 represent a hydrogen atom, a fluorine atom, an alkyl group with 1 to 5 carbon atoms or an alkoxy group with 1 to 5 carbon atoms ). |
