Abstract A novel photoaddressable electronic paper has been developed. It has a spatial light modulator (SLM) structure that consists of microencapsulated cholesteric liquid crystal and an organic photoconductive layer between flexible plastic thin films. An A6‐ size prototype E‐Paper sheet exhibits greater than 20% reflectivity, a 4:1 contrast ratio and a wide viewing angle. Images transferred by the projection of a 2D image with a 200 ms electrical pulse exhibit nonvolatility without power and excellent stability against deformation of the sheet.
