Abstract
This invention relates to a method of fabrication of liquid crystal light modulating devises having electrically tunable spectral wavelength and more particularly, to a cholesteric liquid crystal display with electrically switchable colors. The cholesteric light modulators may be fabricated by applying a plurality of layers to maximize the light modulation. It also features a polymer composite or polymer-network stabilized cholesteric liquid crystal with electrically switchable Bragg reflected wavelength within a predetermined range of spectral wavelength.
