Liquid Crystal color displays for watch application were investigated. Liquid crystal displays using the Guest Host Interaction in conjunction with the cholesteric to nematic phase-change effect have high contrast, but need high electric voltage to drive them. In this paper some surface treatments for alignment and some nematic liquid crystalline hosts were examined to lower threshold voltage and to obtain high contrast. Homeotropic alignment and hybrid alignment had lower threshold voltage than parallel alignment. But because of storage light scattering homeotropic alignmeut isn't so suitable. For parallel alignments, teflon rubbing had the lowest threshold voltage. Contrast ratio was higher for hosts of low birefringence, high order parameter and high dielectric anisotropy.
