Problems solved by technology
[0003] At present, the main disadvantage of negative liquid crystal display is the slow response speed. How to improve the response speed has become an important topic of negative liquid crystal display. Through research, it is found that the reduction of the rotational viscosity of liquid crystal helps to improve the response speed of liquid crystal molecules.

The present invention relates to a liquid crystal composition, in particular to a nematic liquid crystal composition, and more particularly to a pyran-containing liquid crystal composition and application thereof; At least one of the compounds represented by the general formula II; the liquid crystal composition has a low rotational viscosity and a large elastic constant, and then has a low ratio of the rotational viscosity to the elastic constant, which is used in a liquid crystal display. The use of the LCD can significantly improve the response speed of the liquid crystal display and effectively improve the display effect.
Description
technical field [0001] The present invention relates to a liquid crystal composition, in particular to a nematic liquid crystal composition, and more particularly to a pyran-containing liquid crystal composition and application thereof; the liquid crystal composition provided by the present invention has a fast response time , used in liquid crystal displays to improve the response speed of liquid crystal displays. Background technique [0002] In recent years, LCD displays, as the most mainstream displays, have been widely used in various products. Among them, negative liquid crystal displays are widely used in mobile phones, notebook computers, tablet computers, computer monitors, TV, etc. [0003] At present, the main disadvantage of negative liquid crystal displays is the slow response speed. How to improve the response speed has become an important topic of negative liquid crystal displays. Through research, it is found that the reduction of the rotational viscosity of...
