摘要：
This invention relates to a guest-host type liquid crystal composition and a color liquid crystal display device in which said composition has been sealed. This invention provides a liquid crystal composition containing a specific anthraquinone dye as a pleochroic dye which, as the guest dye, has a degree of orderness of the alignment (order parameter) in the host liquid crystal in the range from 0.5 to 1, shows remarkable contrast between the colored state and the uncolored state, and is excellent in stability to light, heat, and the like. Further, this invention provides a color guest-host type liquid crystal display device in which said liquid crystal composition has been sealed.
