Liquid crystals have different elastic properties depending on phases. Twist deformation is allowed in nematic, but not in smectic phase. We showed devices that can create, hide, and manage information using the difference of elastic properties. Information is created in the alignment layer in smectic, expressed as texture in nematic.
