PROBLEM TO BE SOLVED: To provide a liquid crystal medium having a preferable rotation viscosity value, response time, and low-temperature behavior.SOLUTION: There are provided a liquid crystal medium including at least a compound expressed by one formula I, and use of the liquid crystal medium to an active matrix display, especially, to an active matrix display in which VA, PSA, PS-VA, PALC, FFS, PS-FFS, PS-IPS or IPS effect is foundation. (Rand Rare an alkyl group or the like; Zand Zare a connection group such as single binding; and Lare a halogen atom or the like). 【課題】回転粘度値、応答時間、低温挙動が良好な液晶媒体の提供。【解決手段】少なくとも１種類の式Ｉで表される化合物を含む液晶媒体、及びアクティブマトリックスディスプレイ、特にＶＡ、ＰＳＡ、ＰＳ−ＶＡ、ＰＡＬＣ、ＦＦＳ、ＰＳ−ＦＦＳ、ＰＳ−ＩＰＳまたはＩＰＳ効果を基礎とするアクティブマトリックスディスプレイへのこれら液晶媒体の使用。（Ｒ１及びＲ１＊はアルキル基等；Ｚ１及びＺ２は単結合等の連結基；Ｌ１〜３はハロゲン原子等）【選択図】なし
