Abstract

The invention relates to a liquid crystal composition with negative dielectric anisotropy and an application thereof, and belongs to the technical field of liquid crystal materials. The liquid crystal composition comprises a component I, a component II, a component III and a component IV, wherein the component I accounts for 38%-80% by weight, the component II accounts for 18%-60% by weight, the component III accounts for 1%-8% by weight, and the component IV accounts for 0%-6% by weight. The liquid crystal composition disclosed by the invention has a relatively large dielectric anisotropy absolute value, proper optical anisotropy and a wide nematic phase temperature range, can be well applied to a low-voltage LCOS liquid crystal displayer, and can also be suitable for other related liquid crystal wide-temperature display, so that a liquid crystal device can be used in high-heat and high-cold zones, and the problem that a liquid crystal material used by an existing LCOS cannot meet the low-voltage liquid crystal requirement is solved.

Description

technical field [0001] The invention relates to a liquid crystal composition and its application, in particular to a liquid crystal composition with large dielectric anisotropy that can be driven by low voltage and its application, and belongs to the technical field of liquid crystal materials. Background technique [0002] LCOS liquid crystal display (that is, Liquid Crystal on Silicon) is a new product launched in the market in recent years, and it is applied to projection equipment and glasses-type micro-vision display. [0003] LCOS (Liquid Crystal on Silicon) display is a new type of reflective projection display device, which uses semiconductor silicon crystal technology to control liquid crystals and then "projects" color images. LCOS displays have the characteristics of high light utilization efficiency, small size, high aperture ratio, and mature manufacturing technology, and can easily achieve high resolution and full color performance. It can be predicted that LC...
