Abstract

The invention relates to the field of liquid crystal materials and particularly relates to a liquid crystal composite and application thereof. The liquid crystal composite provided by the invention comprises the following components in parts by weight: (1) 1-40 parts of a compound represented by the general formula (I), (2) 10-80 parts of a compound represented by the general formula (II) and (3) 1-50 parts of a compound represented by the general formula (III), wherein the compound represented by the general formula (I) is a compound containing 1,3-dioxane and a difluoromethoxy bridge-bond compound. The liquid crystal composite provided by the invention has low rotary viscosity and large elastic constant, shows relatively short response time and can be used in quick-response liquid crystal displays with a plurality of display modes and display effects of the liquid crystal displays can be significantly improved when the liquid crystal composite is applied in TN-mode, IPS-mode or FFS-mode displays.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a liquid crystal composition containing 1,3-dioxane and a difluoromethoxy bridging compound and its application. Background technique [0002] At present, liquid crystals have been widely used in the field of information display, and at the same time, some progress has been made in the application in optical communication (S.T.Wu, D.K.Yang. Reflective Liquid Crystal Displays. Wiley, 2001). In recent years, the application fields of liquid crystal compounds have been significantly expanded to various display devices, electro-optic devices, electronic components, sensors, etc. Nematic liquid crystal compounds have been most widely used in flat panel displays, especially for TFT active matrix system. [0003] Liquid crystal display has experienced a long development path with the discovery of liquid crystal. In 1888, the Austrian botanist Friedrich Reinitzer discovered the ...
