Abstract

The invention discloses a liquid crystal composition and a display element comprising the liquid crystal composition. The liquid crystal composition contains one or more compounds shown in the generalformula I, the general formula II and the general formula III. The liquid crystal composition has excellent properties, and the optical anisotropy is within the range of 0.080-0.150; moreover, the composition has low rotary viscosity, short response time and good chemical, optical and thermal stability, thereby being quite suitable for producing the liquid crystal display element and particularlysuitable for an active matrix display element, such as an active matrix displayer adopting a VA or FFS or IPS mode.

Description

technical field

[0001] The present invention belongs to the field of liquid crystal compounds, and specifically relates to a liquid crystal composition with negative dielectric anisotropy and a liquid crystal display element using the liquid crystal composition. Background technique

[0002] Display is the process of converting electrical signals (data information) into visible light (visual information). The device that completes the display is the Man-Machine Interface (MMI), and the Flat Panel Display (FPD) is currently the most A popular class of display devices. Liquid Crystal Display (LCD) is the first product developed and commercialized among FPDs. Currently, a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal, TFT-LCD) has become a mainstream product in LCD applications.

[0003] The development of TFT-LCD has gone through a long period of basic research. After realizing mass production and commercialization, TFT-LCD products are bec...
