Abstract

The invention provides a positive-polarity liquid crystal composition. The composition is composed of a component 1, a component 2 and a component 3. The component 1 is composed of a negative polarity liquid crystal composition, the component 2 is composed of a positive polarity liquid crystal composition, and the component 3 is composed of a non-polar liquid crystal composition. The liquid crystal composition has a high vertical dielectric constant value and a wide temperature range while serving as a positive polarity liquid crystal composition, and is beneficial to improving the contrast ratio and light transmittance of a liquid crystal display, improving the quality of a displayed image and saving energy.

Description

[0001] This invention is a divisional case of the prior invention patent with application number 201810570266.8, and the application date is 2018.06.05. This divisional case is written based on the embodiment 13 of the parent case specification. technical field [0002] The invention relates to the field of liquid crystal materials, in particular to a liquid crystal composition and its application. Background technique [0003] In the 1960s, RCA Company first discovered that electrical stimulation could change the light transmission mode of liquid crystals, and then applied this property to release liquid crystal display technology. Then liquid crystals gradually attracted people's attention and rapidly developed into various fields. In 1966, after DuPont synthesized Kevlar fibers using aramid liquid crystals, liquid crystal materials began the process of industrialization. After decades of rapid development, liquid crystal materials have been widely used in many fields suc...
