    摘要: A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

    摘要: A light exposure system is used to expose an alignment layer formed of anistropically absorbing molecules so as to allow alignment of subsequently applied liquid crystal polymer (LCP) molecules. The light incident on the alignment layer is polarized. When a single polarizer is used, the azimuthal polarization direction varies across the substrate carrying the alignment layer. Various approaches to reducing the azimuthal polarization variation may be adopted, including the introduction of various types of polarization rotation reduction element and in selecting an appropriate tilt angle for the light source. Furthermore, a reflective structure may be inserted between the light source and the alignment layer. Use of the reflective structure increases the total amount of light incident on the alignment layer.
