本発明の液晶組成物は、液晶表示素子特にアクティブマトリックス駆動用液晶表示素子として、例えばTNモード、OCBモード、ECBモード、IPS(FFS電極を含む)モード又はVA-IPSモード(FFS電極を含む)に使用することが出来る。ここで、VA-IPSモードとは、電圧無印加時に、誘電率異方性が正の液晶材料(Δε>0)を基板面に対し垂直に配向させ、同一基板面上に配置した画素電極と共通電極により液晶分子を駆動する方法であり、画素電極と共通電極で発生する湾曲電界の方向に液晶分子が配列することから、容易に画素分割やマルチドメインを形成することができ、応答にも優れる利点がある。非特許文献Proc.13th IDW,97(1997)、Proc.13th IDW,175(1997)、SID Sym.Digest,319(1998)、SID Sym.Digest,838(1998)、SID Sym.Digest,1085(1998)、SID Sym.Digest,334(2000)、Eurodisplay Proc.,142(2009)によれば、EOC、VA-IPSなど種々の呼称がされているが、本発明においては以下「VA-IPS」と略称する。
