AbstractLiquid crystal gels, exhibiting promising applications in novel light scattering displays, face the problem of the inherent contradiction between the applied voltage and the contrast, which are the two most basic and crucial parameters for displays. Regretfully, improvement of the applied voltage always means the sacrifice of contrast and vice versa, related to the morphology of the gel fibers. Alternatively, we propose an approach to easily regulate the electro‐optical properties to meet the needs of different applications, towards either lower applied voltage or higher contrast, based on kinetics‐controlled hierarchy self‐assembly. Thin rod‐like and thick helical gel fibers are formed when cooling the liquid crystal gel in water and air respectively, leading to significantly different electro‐optical properties. This method not only facilitates the large‐scale manufacture and application of light scattering displays, but also provides a practical application using the newly developed theory of kinetics‐controlled self‐assembly. © 2021 Society of Chemical Industry
