PROBLEM TO BE SOLVED: To provide a liquid-crystalline medium.SOLUTION: The present invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy (Δε), which is characterized by the fact that it has a value of γ/Δnin the range of 6-45 Pa s, a clearing point greater than 60°C, and Δε less than or equal to -2.3. Media of this type are particularly suitable for electro-optical displays based on the ECB, PA LCD, FFS or IPS effect having an active matrix.SELECTED DRAWING: None 【課題】液晶媒体を提供する。【解決手段】 本発明は、負の誘電異方性（Δε）を有する極性化合物の混合物に基づいた液晶媒体に関し、それは、６〜４５Ｐａ・ｓの範囲のγ１／Δｎ２の値、６０℃を越える透明点および−２．３以下のΔεを有する事実による特徴づけられる。このタイプの媒体は、アクティブマトリックスを備えたＥＣＢ、ＰＡ ＬＣＤ、ＦＦＳまたはＩＰＳ効果に基づく電気−光学ディスプレイに特に適している。【選択図】なし
