Abstract:
1. A cholesteric reflector comprising: a substrate; a first cholesteric layer, the first cholesteric layer being disposed over the substrate, in which the first cholesteric layer reflects a first polarization of light within a design waveband; and a second cholesteric layer being disposed over the first cholesteric layer, in which the second cholesteric layer reflects a second polarization of light within the design waveband; in which the first and second cholesteric layers are treated to substantially align the first and second cholesteric layers with a previously deposited layer; alignment of the first and second cholesteric layers with a previously deposited layer comprising aligning a number of mesogens in the first and second cholesteric layers with a number of mesogens in the previously deposited layer.
