The liquid crystal composition contains one or more compounds selected from compounds as shown in the general formula I-1 and/or general formula I-2; one or more compounds selected from compounds as shown in the general formula II, one or more compounds selected from compounds as shown in the general formula III; and one or more compounds selected from compounds as shown in the general formula IV. The liquid crystal composition provided by the invention has proper optical anisotropy, proper dielectric anisotropy, high clearing point, wide nematic-phase temperature range, fast response speed and good cryogenic storage stability, and is suitable for a liquid-crystal display device. By the use of the liquid crystal composition, the liquid-crystal display device has characteristics of fast response and high reliability, and can normally operate within a wide temperature range.
Description
Technical Field
The present invention relates to a liquid crystal composition, and more particularly, to a liquid crystal composition having suitable optical anisotropy, suitable dielectric anisotropy, a higher clearing point, a faster response speed, and good low-temperature storage stability, and a liquid crystal display device including the same.
Background
The liquid crystal material is a mixture of organic rod-shaped small molecular compounds which have liquid fluidity and crystal anisotropy at a certain temperature. Liquid crystal materials are widely used in liquid crystal display elements of electronic calculators, automobile instruments, televisions, computers and the like because of the characteristics of optical anisotropy and dielectric anisotropy.
The liquid crystal material is divided into normal temperature liquid crystal (the phase transition temperature range is-10-60 ℃) and wide temperature liquid crystal (the phase transition temperature range is-20-70 ℃) according to the phase transition temperature, and liquid crystal displays manufactured by the liquid crystal materials with different phase transition temperatures have different application places. With the continuous expansion of the application range of liquid crystal display devices, people also put higher demands on the working temperature range of the devices to adapt to various severe use environments. In order to expand the operating range of liquid crystal displays, liquid crystal display materials also need to have a wide nematic temperature range to meet the requirement of maintaining good display in various environments.
For liquid crystal displays, liquid crystal compounds and liquid crystal media having good chemical and thermal stability, good stability to electric fields and electromagnetic radiation, suitable optical anisotropy, faster response speed, and lower threshold voltage are in line with the current demand. Since liquid crystals are usually used as a mixture of several components, the mutual solubility of the components is important, and liquid crystals have to meet different requirements, such as electrical conductivity, dielectric anisotropy, and optical anisotropy, depending on the cell type and the application field, but the disadvantages of longer response time, lower resistivity, and too high operating voltage, such as EP0673986, DE19528106, and DE19528107, are significant in the prior art. In addition, poor low temperature storage stability is also a defect of many existing liquid crystal materials, such as WO9732942A 1.
None of the series of compounds having liquid crystalline mesophases disclosed so far includes monomer compounds satisfying all of these requirements, and therefore, in the field of liquid crystal materials, novel liquid crystal compositions having improved properties are required. In particular, for many types of applications, the liquid crystal composition must have a suitably wide nematic phase range, a suitable refractive index, dielectric anisotropy, and low-temperature storage stability.
The invention aims to provide a liquid crystal composition which has a high clearing point, low flow viscosity, a wide nematic phase range and good low-temperature storage stability, can be applied to a liquid crystal element and enables the liquid crystal element to have the characteristics of short response time, high reliability, good low-temperature storage performance and the like.
The response time of the liquid crystal is proportional to the viscosity coefficient of the liquid crystal. The larger the viscosity coefficient of the liquid crystal, the longer the time for the director to transition from one state to another under the influence of an external field or its own elastic force, the slower the liquid crystal will behave as an optical switch.
