摘要:
Provided are a compound represented by the following general formula (1) and a liquid crystal composition containing the compound, and a liquid crystal display device or a light control device having the liquid crystal composition. The compound represented by general formula (1) has both a large dichroic ratio and high solubility in the host liquid crystal. In addition, it has excellent chemical stability at a level usable as a device. Therefore, by using the compound represented by general formula (1) as a component of a GH-type liquid crystal composition, it is possible to provide a liquid crystal display device or a light control device with high contrast.
