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.

Claims (5)

1. A method, 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.

2. The method according to claim 1 , comprising forming a cross-linked polymer layer on the side of the polarisation filter component in direct contact with the dichroic doped polymer active film, and forming the one or more functional layers over the cross-linked polymer layer.

3. The method according to claim 1 , wherein forming one or more functional layers of a liquid crystal device comprises forming a stack of layers defining electrical circuitry for controlling the optical properties of liquid crystal material.

4. The method according to claim 3 , wherein the stack of layers forms at least part of a control component for a liquid crystal display device; and wherein the method further comprises containing liquid crystal material between the control component and a counter component comprising another polarisation filter; wherein the stack of layers defines an array of pixel electrodes independently addressable via conductors of the electrical circuitry outside an active display area.

5. The method according to claim 4 , wherein the electrical circuitry comprises active matrix circuitry.
