A system for processing a multilayer liquid crystal film display material, with
multiple irradiation apparatus (60) for applying a zone of polarized UV
irradiation onto a substrate fed from a web (16) with incident light at
a desired angle. Each irradiation apparatus (60) includes a UV light source
(64), and one or more optional filters (82). A polarizer (90)
is provided, sized and arranged to polarize light over the web (16) as it
moves. The irradiation apparatus (60) employs an array of louvers (81)
and/or a prism array (72). One irradiation apparatus (60) irradiates
a first LPP1 layer (22) at a 0-degree alignment, in the web movement
direction, the other irradiation apparatus (60) irradiates an LPP2
layer (26) with an orthogonal 90-degree alignment.
