Abstract
Film stacks and displays incorporating the same are described. More specifically film stacks that combine a light control film and a color shifting film proximate to one another and, in some embodiments, adhered together are described, as well as displays incorporating such film stacks. Such film stacks may combine the 'blacking out' functionality of a conventional louver film (LCF) and the color shifting effect of a multilayer optical film (MOF).
