Abstract

The invention provides a liquid crystal composition comprising at least a liquid crystal host and at least a chiral dopant. The composition can exhibit a stationary reflection of at least red, green, and blue colors. The composition exhibits reversible color change, faster phototuning time, lower concentration of chiral dopant, and wider color spectrum, among others. The invention also provides a LC device, a method of controlling the stationary reflection of the liquid crystal composition, and a method of processing information.
