Abstract:
1. A liquid crystal composition comprising as a first component at least two compounds selected from the group of compounds represented by formula (1): wherein R 1 is independently alkyl having 1 to 10 carbons or alkenyl having 2 to 10 carbons; R 2 is independently alkyl having 1 to 10 carbons, alkenyl having 2 to 10 carbons, or alkoxy having 1 to 9 carbons; Z 1 is independently a single bond, —C 2 H 4 —, —CH 2 O—, or —CH═CH—; ring A is independently 1,4-cyclohexylene or 1,4-phenylene; n is independently 0 or 1; wherein the liquid crystal composition has a negative dielectric anisotropy; and wherein the liquid crystal composition includes approximately 20% to approximately 60% by weight based on the total weight of the liquid crystal composition of the component of the compound represented by formula (1) wherein n =0 and approximately 40% to approximately 80% by weight based on the total weight of the liquid crystal composition of the component of the compound represented by formula (1) wherein n =1.
