  • Publication number: 20040201816
    Abstract: A method and structure for broadening cholesteric liquid crystals spectrum are described. An electrode structure is added on a side of cholesteric liquid crystals, for producing a fringe field which is perpendicular to a screw axis of the cholesteric liquid crystal. Hence, the thread pitches of cholesteric liquid crystals near the electrode structure are lengthened, but the other thread pitches of cholesteric liquid crystals far from the electrode structure remain the same. Besides, light having appropriate wavelength is used to congeal the cholesteric liquid crystals having a polymeric characteristic, so that the cholesteric liquid crystals have varied thread pitches while no voltage is applied to the electrode structure. Therefore, the spectrum of cholesteric liquid crystals and applications thereof are widened.
