Claims23
A liquid crystal composition which comprises at least one compound selected from compounds represented by Formula (1), at least one compound selected from compounds represented by Formula (2), at least one compound selected from compounds represented by Formula (3), and at least one compound selected from compounds represented by Formula (4), and does not comprise a compound represented by Formula(S),
- in Formula (1) to Formula (4),
- R1, R2, R3, and R4 are hydrogen, a halogen, or C1-12 linear alkyl in which at least one —CH2— may be substituted with —O— or —S—, at least one —(CH2)2— may be substituted with —CH═CH— or —C≡C—, and at least one hydrogen in these groups may be substituted with a halogen;
- L11, L12, L13, L21, L22, L23, L31, L32, L33, L41, L42, L43, L44, and L45 are hydrogen, a halogen, C1-3 alkyl, or C3-5 cycloalkyl;
- Y11, Y21, Y22, Y23, Y31, Y32, Y33, Y34, Y35, Y36, and Y41 are hydrogen or a halogen;
- wherein at least one of L11, L12, and L13 is C1-3 alkyl, at least one of L31, L32, and L33 is C1-3 alkyl, and at least two of L41, L42, L43, L44, L45, and Y41 are not hydrogen,
- in Formula(S),
- RS1 is hydrogen, a halogen, or C1-12 alkyl in which at least one —CH2— may be substituted with —O— or —S—, at least one —(CH2)2— may be substituted with —CH═CH— or —C≡C—, and at least one hydrogen in these groups may be substituted with a halogen;
- LS1, LS2, and LS3 are hydrogen or fluorine;
- and
- YS1 is hydrogen or fluorine.
