ABSTRACT:
The present invention relates to trim retarders used to compensate for residual birefringence created by liquid crystal display panels. In particular the present invention relates to a trim retarder with negative out-of-plane birefringence provided by a form birefringent multi-layer dielectric stack for compensating for retardances resulting from liquid crystal on silicon display panels.
