A liquid crystal medium, comprising at least two liquid crystalline components, wherein at least one component is

• a first dielectrically positive component, component A, comprising one or more dielectrically positive compounds of formula I
• wherein
• R1 is alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy with 1 to 7 C-atoms, alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl with 2 to 7 C-atoms, and preferably are alkyl or alkenyl,
• X1 is halogen, halogenated alkyl or alkoxy with 1 to 3 C-atoms or halogenated alkenyl or alkenyloxy with 2 or 3 C-atoms, and
• optionally, a second dielectrically positive component B,
• a dielectrically neutral component, component C, comprising one or more dielectrically neutral compounds of formula IV
• wherein
• R41 and R42, independently of each other, are alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy with 1 to 7 C-atoms, alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl with 2 to 7 C-atoms
