Abstract

The invention provides a liquid crystal composition which comprises the following components in percentage by weight: (1), 1%-60% of one or more compounds represented by a formula I; (2), 1%-30% of one or more compounds represented by a formula II; (3), 1%-80% of one or more compounds represented by a formula III; (4), 0%-30% of one or more compounds represented by a formula IV; (5), 0%-30% of one or more compounds represented by a formula V. In order to solve the problem that response speed of a liquid crystal display is low due to high viscosity of a liquid crystal material in the prior art, the liquid crystal composition provided by the invention has quicker response time and especially has better low-temperature response time due to low rotary viscosity and great elasticity constant. The liquid crystal composition provided by the invention can be used for quick-response liquid crystal display equipment with a plurality of display modes, and can obviously improve display effects of the liquid crystal display while being used in the display with a TN, IPS or FFS mode.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a liquid crystal composition and its application in the field of liquid crystal displays. Background technique [0002] At present, liquid crystals are 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. For this reason, many different structures have been proposed, especially in the field of nematic liquid crystals, and nematic liquid crystal compounds have been most widely used in flat panel displays so far. Especially for TFT active matrix systems. [0003] Liquid crystal display has experienced a long development path with t...
