Abstract

The invention provides a liquid crystal composition and a liquid crystal display device. The liquid crystal composition comprises at least one compound as shown in a general formula I and at least one compound as shown in a general formula II. Through cooperation of the compounds shown in the general formula I and the general formula II, the composition has a large K value, a fast response speed, a high contrast ratio, a low Flicker and a long low-temperature storage time. The liquid crystal display device containing the liquid crystal composition has the advantages of higher contrast ratio, higher response speed and better low-temperature storage stability.
