Herstellungsverfahren einer chiralen nematischen Flüssigkristallzusammensetzung und Flüssigkristallanzeige |
摘要 |
The present invention is based on a chiral nematic liquid crystal composition which shows cholesteric liquid crystal phase and is able to reflect light in visible region selectively, comprising: a nematic liquid crystal material; a first chiral material with shift direction of selective reflection wavelength toward long wavelength direction depending on temperature; and a second chiral material with shift direction of selective reflection wavelength toward short wavelength direction depending on temperature; wherein at least one chiral material between the first chiral material and the second chiral material comprises two or more chiral compounds, and relates to a preparation method of the above chiral nematic liquid crystal composition and a (layered-type) liquid crystal display using the same. |
