The angular dependence of light scattering in nematic-cholesteric mixtures with positive dielectric anisotropy was measured; the quiescent transparent satate S, the focal-conic state F, the storage focal-conic state F_o, and the field-induced nematic state H were investigated. The F_o state showed Bragg scattering peaks caused by the lattice spacing of P_o/2 where P_o was the helical pitch of the mixture used. While, the light scattering profile for the F state under an applied electric voltage was found to be characterized by scattering peaks caused by the optical lattice spacing of P_o itself, though the detailed physical reason has not yet been fully understood. The contrast ratio of the light scattering between F_o and S was also discussed in connection with application to storage-type liquid crystal displays.
