| titleOfInvention | Method for producing polarization-diffractive cholesteric liquid crystal film |
| abstract | (57) [Problem] To provide a method for producing a polarization diffractive cholesteric liquid crystal film in which diffracted light itself generates specific polarized light such as circularly polarized light or linearly polarized light. SOLUTION: The weight average molecular weight Mw measured by GPC (in terms of polystyrene) on an orientation support substrate is 1000 to 10 10,000, a molecular weight distribution (Mw / Mn; Mn is a number average molecular weight) of 5 or less, and a logarithmic viscosity of 0.05 to 2.0 (a concentration of 0.5 g / dl in a phenol / tetrachloroethane (weight ratio 60/40) mixed solvent). (Temperature 30 ° C.)) and a film material containing a polymer liquid crystal having a glass transition temperature (Tg) of 200 ° C. or less and a transition temperature (Ti) from a liquid crystal phase to an isotropic phase of 40 ° C. or more as an essential component. A first step of forming a cholesteric liquid crystal film, a second step of transferring a diffraction pattern of a diffractive element substrate to a cholesteric liquid crystal film surface and forming a region exhibiting diffractive ability in a part of the film, and an alignment support substrate from the cholesteric liquid crystal film. A cholesteric liquid crystal film having a polarization diffractive property, comprising a third step of peeling off the cholesteric liquid crystal film. |
