Abstract: Liquid crystal modulator optical devices and more specifically shutters and smart windows are presented. The liquid crystal modulator devices are characterized by a reduced polymer content which is eliminated from the material composition of the liquid crystal layer and characterized by non-uniform electrode structures in the liquid crystal structure configured to generate spatially non-uniform electric fields and therefore non-uniform molecular reorientation of liquid crystal molecules. This arrangement advantageously makes light scattering electrically controllable.

Abstract: An identification medium cannot be reused when an attempt has been made to remove it from an object by using solvent. A cholesteric liquid crystal layer subjected to a hologram processing is formed while contacting a COP (cycloolefin polymer) layer. When the identification medium is removed using a solvent from a state in which it was adhered to an object by an adhesive layer, the COP layer is melted by the solvent and is damaged. The COP layer is a layer which functions as a substrate of the identification medium, and the identification medium is damaged by contacting with the solvent, as described above, and it is difficult to reuse.
