Abstract
The invention relates to a polarization compensating element (PCE) for a liquid crystal, e.g. liquid crystal on silicon (LCoS), display system manufactured using a linearly photo-polymerizable polymer (LPP) for orienting a photo-polymerizable liquid crystal polymer (LCP) film. To decrease the reflection, polarization conversion, and interference events in an LPP/LCP assembly the ΔN birefringence value of the LCP material is minimized. Dielectric coatings are added at various locations throughout the assembly for minimizing the amount of reflection, polarization conversion, and interference effects and for suppressing spatial retardance ripples.
