Abstract

The invention relates to a compound, a liquid crystal medium, a liquid crystal display element and a liquid crystal display. The structural formula of the compound is shown as a formula I in the specification. The compound can be used as a liquid crystal compound; and by using the compound, the clearing point of liquid crystal molecules is further improved on the basis of maintaining good rotary viscosity. Besides, the compound disclosed by the invention is used in a liquid crystal composition, and low-temperature intersolubility is good, so the working temperature range of the liquid crystalcomposition is wide.

Description

technical field

[0001] The invention belongs to the field of liquid crystal display. Background technique

[0002] Liquid crystals have been widely used since commercially available liquid crystal compounds were first discovered about 30 years ago. Known fields of application of conventional mixtures are in particular displays for watches and pocket calculators, and large display panels used in railway stations, airports and stadiums. Additional areas of application are displays for laptop and desktop computers, navigation systems and video applications.

[0003] In order to make the performance of the display device closer to the ideal, people have been working on researching new liquid crystal compounds, which enables the performance of the liquid crystal compound and the display device to continue to develop.

[0004] In Patent Document 1, the following compounds for liquid crystal media are disclosed:

[0005]

[0006] where R 1 and R 2 represents an alkyl group....
