| abstract |
The invention relates to a liquid crystal medium which contains at least one compound of the formula (I), in which R 1 and R 1* independently of each other represent an alkyl or alkyl group with 1 to 15 C atoms, wherein in said groups, one or more CH 2 groups independently of one another can be replaced with -C=C-, -CF 2 O-, -OCF 2 -, -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 L 1 and L 2 independently of one another represent F, Cl, CF 3 , or CHF 2 . 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. |
