Abstract

The invention relates to a liquid crystal compound, a liquid crystal display element including the liquid crystal compound and a liquid crystal display and belongs to the field of liquid crystal display. The liquid crystal compound provided by the invention comprises one or more compound shown as formula I, one or more compound selected from a group composed of compounds shown as formula II A, formula II B, formula II C, formula II D and formula II E, and the compound shown as formula III. The liquid crystal compound is capable of improving incidental image defect, is characterized by excellent ultraviolet resistance and high temperature resistance, and has moderate or higher optical anisotropism delta n, lower viscosity, wider nematic phase temperature range and excellent low-temperaturesolubility.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and more specifically relates to a liquid crystal composition, and a liquid crystal display element or a liquid crystal display containing the liquid crystal composition. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. People have higher and higher requirements for liquid crystal flat panel displays. Therefore, higher requirements are placed on the quality characteristics of liquid crystal materials used in liquid crystal flat panel displays. [0003] During the use of the liquid crystal display, the liquid crystal composition will be continuously ...
