A preparation method for a temperature-responsive light reflecting coating is provided comprising: forming a main chain cholesteric phase liquid crystal polymer by a polymerization reaction between an acrylate liquid crystal and an amine, and coating the main chain cholesteric phase liquid crystal polymer on a substrate to form a light reflecting coating, wherein the acrylate comprises a chiral acrylate, and the reflection wavelength of the reflecting coating is determined by the content of the chiral acrylate liquid crystal and the polymerization degree of the main chain cholesteric phase liquid crystal polymer formed. The method may further comprise cross-linking the main chain cholesteric phase liquid crystal polymer to obtain a polymer network so as to form a solid coating. The present disclosure further provides a temperature-responsive light reflecting coating. The preparation of the main chain cholesteric phase liquid crystal polymer of the present disclosure requires only a simple thermally-driven polymerization reaction.

A liquid crystal composition includes at least one compound of general Formula I, at least one compound of general Formula II and at least one compound of general Formula M. The polymerizable liquid crystal composition provides a higher VHR (especially an excellent VHR after UV irradiation), a lower surface roughness of the polymer layer, a faster polymerization rate, a lower residual amount of the polymerizable compound and a better pretilt angle stability, which enables the production of a liquid crystal display device with a better voltage stability and a faster response speed, and can effectively reduce or prevent the occurrences of problems such as “burn-in”, “image sticking”, “Zara Particle” and “uneven display” in the liquid crystal display device. A liquid crystal display includes the liquid crystal composition.

The present disclosure provides a liquid crystal material, a method of manufacturing a liquid crystal display panel, and a display panel. The display panel includes a thin film transistor substrate, a color film substrate, a polymer layer structure, and a liquid crystal layer. During the preparation, after three different irradiations, the liquid crystal material is directly polymerized into the first polymer layer structure and the second polymer layer structure under the irradiations, eliminating the black matrix structure and the polyimide alignment film structure, improving the display effect of the panel, and reducing preparation costs.
