The complex-shape solid-state cholesteric liquid crystal (CLCsolid) droplets were prepared with phase separation and photopolymerization of the uniformly-sized reactive CLC (rCLC)/fluorocarbon oil (FCO) mixture droplets which were produced by a microfluidic method. The assembly of the complex-shape rCLC/FCO droplets showed the complex photonic reflection pattern consisting of central reflection, cross communication among the adjacent particles, and total reflection. These complex patterns make the complex-shape CLCsolid and the rCLC/FCO droplets ideal candidates for anti‐counterfeiting materials compared with the traditional pattern from ordinary spherical droplets
