Patent ID: 6936312

Claim:
A liquid crystal composition comprising a first component consisting of at least one compound selected from a group of compounds represented by Formula (I) and a second component consisting of at least one compound selected from a group of compounds represented by Formulas (II-1) to (II-8): wherein R 1 and R 2 are independently alkyl having 1 to 10 carbons, alkoxy having 1 to 10 carbons or alkenyl having 2 to 10 carbons; X 1 to X 12 are independently hydrogen or fluorine, and at least two of X 1 to X 12 are fluorine; when one 1,4-phenylene has two fluorines, the positions of fluorines are 2- and 5-positions or 2- and 6-positions; and n is 0, or 1, and wherein R is alkyl having 1 to 10 carbons; A is 1,4-phenylene or 1,4-cyclohexylene; X 1 , X 2 and X 3 are independently hydrogen or fluorine; Y 1 is fluorine or —OCF 3 , and Y 2 is fluorine or chlorine; Z is a single bond or —C 2 H 4 —; and n is 0 or 1.
