Liquid crystal material is a substance with both liquid and crystal properties, which is widely used in modern display technology, especially in liquid crystal display (LCD). Its uniqueness comes from the controllability of the molecular arrangement: liquid crystal molecules are usually linear in shape and can change their orientation under the action of an electric field, thus affecting the direction of light propagation.

In an LCD, the liquid crystal material is sandwiched between two glass substrates that are covered with transparent electrodes and a special alignment film. By applying different voltages, the arrangement of liquid crystal molecules changes, regulating the amount of light that passes through. Combined with backlight and filters, liquid crystal materials can produce rich colors and clear images.

Liquid crystal materials are divided into several types, the most common Nematic liquid crystal, which is used for ordinary LCD displays, and Cholesteric liquid crystal, which is used for specialty displays or reflective screens. Nematic liquid crystal is the mainstream choice of modern display technology because of its fast response speed and precise control.

Liquid crystal display technology with its low power consumption, thin and high resolution advantages, has become one of the core technologies of TV, computer, smart phone and other devices. The continuous improvement of liquid crystal materials is also promoting the development of displays in the direction of higher brightness, wider viewing Angle and lower energy consumption.
