Cholesteric liquid crystals

Cholesteric liquid crystals, also known as chiral nematic liquid crystals, are a special type of liquid crystal where the molecules are arranged in layers that twist gradually, creating a helical structure. This ordered, repeating pattern reflects specific wavelengths of light, giving them unique optical properties, such as vibrant colors that can change with viewing angle or temperature. They are used in display technologies, like e-readers, and in optical devices due to their ability to manipulate light precisely. Their distinctive helical arrangement results from the molecules’ chirality, or "handedness," influencing how they interact with light.
