[0004] The development of TFT-LCD TV has entered an era of large size, wide viewing angle, and fast response. TN+Film, In Plane Switching (IPS) and Fringe Field Switching (FFS) technologies are known for their close to 180o The wide viewing angle has always attracted attention, and with the expansion of application fields and scopes (such as outdoor applications, high and low temperature environments, high definition, longer life), it is difficult for existing technologies to meet these applications

Abstract
The invention provides a liquid crystal composition. The liquid crystal composition comprises the following components by weight percentage: 1, a first component comprises compounds which are represented by a general formula I and a general formula II, the content of the first component is 1-65%, and preferentially is 35-65%; 2, a second component comprises compounds which are represented by a general formula III, a general formula IV and a general formula V, the content of the second component is 1-60%, and preferentially is 30-60%; and 3, a third component comprises compounds which are represented by a general formula VI and a general formula VII, the content of the third component is 1-55%, and preferentially is 5-35%. The liquid crystal composition has the characteristics of fast response time, low rotary viscosity, high-definition bright spot, high dielectric anisotropy and high transmittance and can well meet the rigorous requirements of a shutter mirror and display devices such as 3D (three dimension), TN (twisted nematic), STN (super twisted nematic), TN-TFT(twisted nematic-thin film transistor), OCB (optically compensated birefringence), IPS (in-plane switching), PS-IPS (-in-plane switching), VA-IPS (vertical alignment-in-plane switching), FFS (fringe field switching), PS-FFS (-fringe field switching), PS-VA-IPS (polymer stabilized-vertical alignment-in-plane switching) and the like.
Description
technical field [0001] The invention belongs to the field of liquid crystal materials, and in particular relates to a liquid crystal composition which can be used in various modes. Background technique [0002] Basic research on the basic properties and basic theories of liquid crystals started earlier, and the use of liquid crystal materials in display technology was the earliest in 1968. Heilmeier and others at the Princeton Research Institute of RCA Corporation in the United States invented the dynamic scattering (Dynamic Scattering, DS) mode of liquid crystals. LCD Monitor. In 1971, M. Schadt et al. published the Twisted Nematic (TN) effect of liquid crystals; in the same year, M. Schiekel et al. and M. Hareng et al. published the Electrically Controlled Birefringence (ECB) mode almost simultaneously. Subsequently, the guest-host (Guest Host, GH) effect, phase change (Phase Chang, PC) effect, super twisted nematic (Super TN) and other effects were discovered one after a...
