Abstract
The invention relates to a method of preparing a broadband reflective polarizer comprising the blending a first mixture A comprising at least one achiral polymerizable mesogenic compound with a second mixture B comprising at least one chiral polymerizable mesogenic compound; and coating a layer of the blended mixture onto a first substrate and aligning the chiral mesogenic material in a planar orientation so that the axis of the molecular helix extends transversely to the layer.
