Claim 0:
1. A light control film having a series of louver structures, wherein each louver structure includes a one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix comprising an optically cured material, the optically cured material having a viscosity of less than about 1350 cps at 25 degrees Celsius prior to curing,
wherein the light control film substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle,
wherein each louver structure is spaced apart from an adjacent louver structure by from about 0.05 mm to about 5 mm, wherein each louver structure is aligned in a plane substantially parallel to an adjacent louver structure, and
wherein each louver structure is oriented at a louver angle from about 0° to about 50° from a normal to a light incident surface of the light control structure.
