Abstract Cholesteric liquid crystals (CLCs), a class of photonic materials with multi‐stimulus response and tunable bandgaps (PBGs), exhibit the characteristics selective circularly polarized reflection properties due to helical assembly supramolecules. To enhance their practical applicability, CLCs can be uniformly dispersed as microdroplets within polymer matrices, forming cholesteric (PDCLCs). This composite system not only provides essential mechanical stability but also enables enhanced multimodal responses through matrix interactions. PDCLC have been widely used in fields dynamic displays, intelligent sensors, anti‐counterfeiting systems optical encryption devices. review comprehensively surveys fundamental properties, preparation methods, field‐responsive behaviors major applications PDCLCs. Furthermore, current challenges future developments PDCLCs are prospected further promote scientific research application materials.
