| abstract |
The present invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I wherein R 1 and R 1 * in each case independently of one another an alkyl or alkoxy radical having 1 to 15 C atoms, where in these radicals also one or more CH 2 groups are each independently of one another by -C≡C-, -CF 2 O-, -OCF 2 -, - CH = CH-, -O-, -CO-O-, -O-CO- can be replaced so that O atoms are not directly linked to one another, and in which also one or more H atoms can be replaced by halogen, L 1 and L 2 each independently of one another F, Cl, CF 3 or CHF 2 , mean, contains and its use for an active matrix display, in particular based on the VA, PSA, PA-VA, SS-VA, SA-VA, PS-VA, PALC, IPS, PS-IPS, FFS or PS-FFS effect. |
