Abstract
Disclosed are a liquid crystal composition, a liquid crystal display element, and a liquid crystal display, said liquid crystal composition comprising one or more compounds represented by formula I, one or more compounds represented by formula II, one or more compounds represented by formula III and one or more compounds represented by formula IV, The liquid crystal composition of the present invention has a good stability to light and heat and a lower viscosity, and can attain a wider refractive index and a high clearing point (a wide service temperature range), and in particular, the liquid crystal composition has a high light transmittance, thus allowing a display device to have a high brightness or an energy saving effect.
