Liquid crystals, as the name suggests, are liquid crystals, and the discovery of liquid crystals dates back to the end of the 19th century.
In April 1888, Austrian botanist Frederick Renizel first observed liquid crystals and synthesized a substance, which was later identified as a crystal by German physicist Otto Lehmann and named it "" Liquid crystal", so on May 3, 1888, liquid crystal had its own official name in the field of science. But Renizel found only its properties of fluidity, two melting points and optical rotation. Lyman began a systematic study of liquid crystals. He observed the polarization phenomenon of liquid crystal, the orderly arrangement of crystal structure and optical anisotropy under the microscope. In 1889, Lehmann published his observations in the German journal "Physical Chemistry".

80 years later, it was discovered that liquid crystals had strange uses in displays. In flat panel electrical devices, the liquid crystal display was an instant hit, and immediately became a research hotspot in the global electronics field, and it also became a business opportunity that merchants could not ignore. The research on LCD flat panel display originated in 1961. Radio Corporation of America George Haimel discovered in his experiments that the liquid crystal layer changed from red to transparent when a voltage was cleverly applied, a discovery that made him a pioneer in the development of liquid crystal screens.

In 1966, Joel Goldmacher found a new type of liquid crystal material, which for the first time brought liquid crystal into the use range of electronic equipment; in 1969, German chemist Hans Kerke developed a standard liquid crystal practical material - butyl Aniline (MBBA), contributed to the amazing development of the microelectronics industry. Today, liquid crystal displays can not only display video signals, but also have the advantages of long service life, fast response speed, long viewing distance, high brightness, large viewing angle, digitization and high image resolution.
