    摘要： An alignment layer may align molecules of a liquid crystalline material to a surface of a substrate having a diffractive optical power region using a nonlinear alignment. The alignment layer may align the molecules of the liquid crystalline material in one of a tangential alignment, a piecewise tangential alignment, a perpendicular alignment, a piecewise perpendicular alignment, a continuous intra-zone alignment, or a piecewise continuous intra-zone alignment. The nonlinear alignment may result in optimal or near optimal alignment of the liquid crystalline material thereby resulting in improved optics and fewer vision compromises.

    摘要： Embodiments of the present invention relate to a cholesteric liquid crystalline material which may be usable in an electro-active element for providing fail safe operation, polarization insensitivity, low electrical power consumption requirements, and a small number of electrical connections. The cholesteric liquid crystalline material may be usable in an electro-active element for providing a diffractive efficiency or focusing efficiency above 90% in an activated state of the electro-active element and a diffractive efficiency or focusing efficiency below 10% in a deactivated state of the electro-active element.
