The present invention relates to the field of liquid crystal materials, and specifically discloses a liquid crystal composition containing a 1,3-dioxane compound and application of the same in a liquid crystal display device. The liquid crystal composition of the invention comprises the following components in parts by weight: 1-24 parts of one or more compounds selected from compounds represented by the formula (I), 1-80 parts of one or more compounds selected from compounds represented by the formula (II), 1-35 parts of one or more compounds selected from compounds represented by the formula (III), and 0-40 parts of one or more compounds selected from compounds represented by the formula (IV). An optical birefringence delta n of the liquid crystal composition is between 0.08 to 0.15, and has a moderate refraction range. The liquid crystal composition provided by the invention not only has characteristics like a broader nematic temperature range, a high resistivity, a high charge holding rate, and a low viscosity, but also has a faster response speed and good cryogenic storage stability. When the liquid crystal composition is applied to a liquid crystal display, particularly a display of the TFT-LCD mode, the display effect of the liquid crystal display can be improved significantly.
Description
technical field [0001] The invention relates to the field of liquid crystal materials, and specifically discloses a liquid crystal composition containing a 1,3-dioxane compound and its application in a liquid crystal display device. Background technique [0002] Liquid crystal material is a mixture of organic rod-shaped small molecular compounds that have both fluidity of liquid and anisotropy of crystal at a certain temperature. Liquid crystal display devices work by utilizing the optical anisotropy and dielectric anisotropy of the liquid crystal material itself, and have been widely used at present. Using different characteristics and working modes of liquid crystal materials, devices can be designed in different working modes, mainly including the following: dynamic scattering (dynamic scattering, DS) type, electric field controlled birefringence (electrically controlled birefringence, ECB) type, twisted Nematic (twisted nematic, TN) type, ferroelectric liquid crystal (F...
