| abstract |
The present invention relates to a liquid crystal composition containing a dichroic dye that achieves the required characteristics such as a large dichroic ratio, high contrast, high solubility, and clear color, and a liquid crystal display device or a control using the same. The present invention relates to an optical element. By using the liquid crystal composition of the present invention, it is possible to provide a liquid crystal display element or a light control element having high practicality as well as high display quality such as high contrast and good black appearance. The liquid crystal display element using the liquid crystal composition of the present invention is useful for a liquid crystal display element for active matrix driving, and is used for a liquid crystal display element for PSA mode, PSVA mode, VA mode, TN mode, STN mode, and IPS mode. it can. |
