PROBLEM TO BE SOLVED: To provide a super twisted liquid crystal display having a short switching time, and at the same time, a wide operating temperature range, a sharp rising of a characteristic curve, a good angle dependence of contrast, and a low threshold voltage. A liquid crystal mixture is provided. The liquid crystal mixture is based on one or more compounds of the formula I, II, and / or III, and a compound of the formula B1VIII. Embedded image In these formulas R 1 represents alkyl having 1-12 carbon atoms, provided that one or two non-adjacent CH 2 groups are —O—, —CH = CH—, —CO—, — O-CO- or -CO-O- R is O or 1; s is 0, 1 or 2; each ring A 1 and A 2 is independently of each other trans-1,4-cyclohexylene, 1,4 -Phenylene or 3-fluoro-1,4-phenylene, A 3 Is Wherein Q is OCHF, OCF 2 , CF 2 or a single bond, and Y is Is H, F or C1, L is H or F, and ring C is Represents |
