LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE THEREOF

摘要

Provided is a liquid crystal composition, comprising: one or more compounds of general formula I accounting for 1-30% of the total weight of the liquid crystal composition; one or more compounds of general formula II accounting for 1-30% of the total weight of the liquid crystal composition; one or more compounds of general formula III accounting for 1-20% of the total weight of the liquid crystal composition; and one or more compounds of general formula IV accounting for 30-80% of the total weight of the liquid crystal composition. The liquid crystal composition has at least one of the following properties: a large specific resistance, a high voltage holding ratio, a suitable optical anisotropy, a large dielectric anisotropy, a small viscosity, a low threshold voltage, etc., and is also green and environmentally friendly. The liquid crystal composition is suitable for use in a liquid crystal display device, enabling the liquid crystal display device to have the following properties: a high voltage holding ratio, a short response time, a high contrast ratio, a low energy consumption, and being green and environmentally friendly, etc.
