Description

technical field

[0001] The invention relates to the field of liquid crystal displays, in particular to a compound, a liquid crystal composition and a liquid crystal display. Background technique

[0002] According to different display methods, liquid crystal displays are divided into dynamic flash type, twisted type, super twisted type and plane conversion type. Although different types of liquid crystal displays require liquid crystal compositions to have different properties, they are also required to have the following common features: proper optical anisotropy, proper rotational viscosity and fast response speed.

[0003] The liquid crystal composition is prepared by mixing various liquid crystal compounds, so the properties of the liquid crystal compound monomers are particularly important. Due to the low clearing point of the existing liquid crystal composition, it cannot meet the requirements of liquid crystal displays used at high temperatures, and has the problem o...
