Optical Compensators by Polymer Stabilization Technique (DISP, FILM)

 KSU.248

Abstract: The present invention provides a method of preparation of optical compensation films using a polymer stabilization technique so as to enable continuous roll-to-roll production.  The films can be applied for reflective liquid crystal displays.  They are prepared by photo polymerizing a mixture comprising a reactive monomer (or mixture of monomers), a small amount of photoinitiator and liquid crystal.  The concentration of the reactive monomer (mesogenic or non-mesogenic) in the reactive mixtures can be as low as 5% or as high as 99% by weight.  The materials that can function as the optical compensation films in the present invention include, but are not limited to, mixtures of liquid crystal and reactive mesogenic monomers (rod-like, bent-shaped, and disc-like mesogenic monomers) containing polymerizable groups (monofunctional or multifunctional) selected from acrylate, methacrylate, vinyls, butadiene, vinyl ethers, or epoxide.
