ABSTRACT:
The present invention provides a polarizing holographic reflector module useful in the manufacture of a holographically-illuminated liquid crystal display assembly by combination thereof with a partial LCD stack. The polarizing holographic reflector module is substantially quadrangular in shape and comprises a reflective holographic diffuser, a light polarizer, a pressure sensitive adhesive, and a removable protective liner. A method of manufacture is also provided wherein a web of polarizer material having a linear or downweb orientation is roll-to-roll laminated to a web of angularly offset reflective holographic diffusers.
