Liquid crystalline medium

The invention relates to a liquid crystal medium which contains at least one compound of the formula (I), in which R1 and R1* independently of each other represent an alkyl or alkyl group with 1 to 15 C atoms, wherein in said groups, one or more CH2 groups independently of one another can be replaced with -C=C-, -CF2O-, -OCF2-, -CH=CH-, formula (II), formula (III), -O-, -CO-O-, or -O-CO- such that O atoms are not directly linked to one another, and one or more H atoms can also be replaced with halogen, and L1 and L2 independently of one another represent F, Cl, CF3, or CHF2. The invention also relates to the use of said liquid crystal medium for an active matrix display, in particular an active matrix display based on the VA-, PSA-, PA-VA-, PS-VA-, PALC-, IPS-, PS-IPS-, FFS-, or PS-FFS effect.
