Liquid crystal composition containing one or two or more compounds represented by formula (L) and three or four or more dichroic dyes selected from azo compounds, and guest host type using the same The liquid crystal display device or the light control device of The liquid crystal composition of the present invention can simultaneously satisfy high contrast, high solubility, high nematic-isotropic transition temperature (TNI), and low birefringence anisotropy (Δn) effective for high light resistance and high heat resistance. It is a liquid crystal composition containing a colorable dye, and by using the liquid crystal composition of the present invention, a liquid crystal display element or a tone having high practicability with high contrast and high display quality, exhibiting a good black appearance. An optical element can be obtained. |
