Abstract
A technique, comprising: removing a protective film from one side of a polarisation filter component to expose a dichroic doped polymer active film or a layer formed in situ on the dichroic doped polymer active film; and thereafter forming in situ on the side of the polarisation filter component one or more functional layers of a liquid crystal device.
