Patent ID: 8075960

Claim:
A liquid crystal composition having a nematic phase that includes three components, wherein the first component is at least one compound selected from the group of compounds represented by formula (1), and the second component is at least one compound selected from the group of compounds represented by formulas (2-1) and (2-2), and the third component is at least one compound selected from the group of compounds represented by formula (3); the ratio of the first component is in the range of approximately 20% to approximately 50% by weight, the ratio of the second component is in the range of approximately 10% to approximately 35% by weight, and the ratio of the third component is in the range of approximately 5% to approximately 45% by weight based on the total weight of the liquid crystal composition. wherein R 1 and R 2 are independently alkyl having 1 to 12 carbons, or alkenyl having 2 to 12 carbons; R 3 and R 4 are independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, or alkenyl having 2 to 12 carbons in which arbitrary hydrogen is replaced by fluorine.
