Liquid crystal composition containing an optically active compound and liquid crystal electro-optical element |
| 摘要 |
It is to provide a liquid crystal composition containing at least one type of optically active compounds of the following formulae (1) to (4), and a liquid crystal electro-optical element excellent in display quality. In each formula, C* is asymmetric carbon, and the respective symbols are as defined in description <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>-A<SUP>1</SUP>-C*HX-Y-A<SUP>2</SUP>-(Z<SUP>1</SUP>-A<SUP>3</SUP>)<SUB>m</SUB>-C≡C-A<SUP>4</SUP>-(Z<SUP>2</SUP>-A<SUP>5</SUP>)<SUB>n</SUB>-R<SUP>2</SUP> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>-A<SUP>1</SUP>-C*HX<SUP>1</SUP>-Y<SUP>1</SUP>-A<SUP>2</SUP>-Z<SUP>1</SUP>-A<SUP>3</SUP>-Z<SUP>2</SUP>-A<SUP>4</SUP>-R<SUP>2</SUP> (2)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>5</SUP>-Pn-C*HX<SUP>2</SUP>-CH<SUB>2</SUB>-A<SUP>6</SUP>-Y<SUP>2</SUP>-A<SUP>7</SUP>-R<SUP>6</SUP> (3)<?in-line-formulae description="In-line Formulae" end="tail"?>
