(57) [Abstract] [Purpose] A liquid crystal composition having appropriately high Δn and low viscosity for STN display mode. [Structure] First component (3-40%) and second component (30 -97%). First component: compound of formula (I), second component: compound of formula (II). Embedded image In the formula, R 1 , R 2 and R 3 represent alkyl having a C number of 1 to 10 or alkenyl having a C number of 2 to 10, and in each case, any one of the groups or two or more methylenes which are not adjacent to each other. may be replaced by -O-, Z 1 is -CH 2 C H 2 -, - COO- or a single bond, Q 1 and Q 2 H Or F, (A) represents trans 1,4-cyclohexylene, 1,4-phenylene or trans-1,3-dioxane-2,5-diyl, and m represents 0 or 1. |
