Liquid crystal medium with positive dielectric anisotropy comprises one or more 4-cyclohexyl-2-fluoro-benzonitrile derivatives (I) and/or one or more 1-alkenyl-4-cyclohexyl-cyclohexane derivatives (II). Liquid crystal medium with positive dielectric anisotropy comprises one or more compounds of formula (I) and/or one or more compounds of formula (II). R<1> = 1-12C alkyl, 1-12C alkoxy, 2-12C alkenyl, 2-12C alkoxyalkyl or 2-12C alkenyloxy; L = H or F; R<21> = 1-7C alkyl, 1-7C alkoxy, 2-7C alkenyl, 2-7C alkoxyalkyl, 2-7C alkenyloxy, F, Cl, OCF3 or OCF2H; R<22> = H or 1-10C alkyl; Y<21>, Y<22> = H or F; n = 0-5; and m = 0 or 1. Independent claims are also included for the following: (1) An electro-optic display element containing the liquid crystal medium. (2) An electro-optic display comprising one or more of these elements. |
