Disclosed are a polymer-stabilized liquid crystal composition and the use thereof. The composition comprises one or two polymerizable compounds represented by general formula I: (I), and further comprises a negative dielectric anisotropy liquid crystal composition, wherein the negative dielectric anisotropy liquid crystal composition has a dielectric anisotropy of Δε≤−1.5; and the added amount of the polymerizable compound(s) represented by general formula I is 0.1-0.5% of the total mass of the negative dielectric anisotropy liquid crystal composition. A polymer film formed after the polymerization of the provided liquid crystal composition containing the polymerizable compound(s) has a very good uniformity, such that the problem of liquid crystal displays having poor display can be improved. Moreover, an alignment film formed after the polymerization of the polymerizable liquid crystal composition has an excellent alignment force, and can improve residual image problems caused by an insufficient alignment force in a PSVA liquid crystal display. The provided liquid crystal composition containing the polymerizable compound(s) can realize an adjustable response speed, and can in turn meet the requirements of different technical process conditions.

Polymer-stabilized liquid crystal composition and use thereof

The present invention provides a novel liquid crystal material composition comprising one or more compound, in order to achieve the properties of low viscosity, high resistivity, good low-temperature mutual solubility, fast response, excellent transmission, and which can be used for a variety of fast response display modes. Since the working temperature of a LCD material is subjected to the temperature range of individual LC molecules, information can only be displayed in a specific temperature range of the specific liquid crystal macro-alignment phase. At low temperature, the viscosity of liquid crystal increases exponentially, which in turn substantially reduces the response speed and overall performances of the display system. The liquid crystal composition according to the present invention overcomes these problems with balanced chemical composition by achieving low viscosity, good low-temperature performance and excellent transmission in a wide range of LCD applications including TN, IPS or FFS displays, thus improving display performance.

Liquid crystal composition and its application

A liquid crystal composition and use thereof in the liquid crystal display field. The liquid crystal composition includes, in percentages by weight, 5-40% of one or more compounds represented by general formula I, 2-30% of one or more compounds represented by general formula II, and 20-70% of one or more compounds represented by general formula III, and may further include 4-30% of one or more compounds represented by general formula IV and/or 5-25% of one or more compounds represented by general formulas V to IX. The combined use of the above-mentioned compounds can effectively reduce the rotational viscosity of the liquid crystal composition, improve related properties of the mixed liquid crystal, and thus reduce the response time thereof. The liquid crystal composition can be used for a fast-response liquid display in a variety of display modes.

Liquid crystal composition and application thereof

The present invention relates to the technical field of liquid crystal displays, and particularly relates to a liquid crystal composition containing a 2-methyl-3,4,5-trifluorobenzene liquid crystal compound and use thereof, wherein the liquid crystal composition of the present invention comprises, in percentages by weight, 1-50% of one or more compounds represented by general formula I and 10-70% of one or more compounds represented by general formula II, and may further comprise 0-30% of compounds represented by general formula III and/or 6-45% of one or more compounds represented by general formulas IV to XIII. The liquid crystal composition provided by the present invention has a low rotational viscosity and a large elastic constant, is presented as having a shorter response time, and can significantly improve the display effect of a liquid crystal display when applied to TN, IPS and FFS mode displays.
