The present invention relates to a liquid crystal medium comprising at least one compound of formula (I), and more specifically, to a use thereof for active-matrix displays based on VA, PSA, PS-VA, PALC, FFS, PS-FFS, PS-IPS or IPS effects. In the above expression, R_1, R_1*, Z_1, L_1 and L_2 have the meanings set forth in claim 1. The invention is based on the object of providing liquid crystal mixtures for monitor and TV products, in particular, based on the ECB effect or the IPS or FFS effect. 본 발명은 하기 화학식 I의 화합물 하나 이상을 포함하는 액정 매질, 및 특히 VA, PSA, PS-VA, PALC, FFS, PS-FFS, PS-IPS 또는 IPS 효과에 기초한 능동-매트릭스 디스플레이를 위한 이의 용도에 관한 것이다: JPEGpat00285.jpg2063 상기 식에서, R1, R1*, Z1, L1 및 L2는 특허청구범위 제 1 항에 제시된 의미를 갖는다.
