Abstract
A diffuse reflector (100) uses a host layer (120) containing particles (122). The host layer (120) contains a cholesteric material that reflects a first frequency of light, and the particles (122) in the host layer (120) create separate cholesteric domains (126) that reflect light of the first frequency in different directions.
