A liquid crystal storage device includes a smectic phase liquid crystalline medium in spaced relationship with at least three separated electrodes, the first of which provides a ground plane and is in contact with the liquid crystal medium; a second electrode, spaced from the first electrode, is arranged in a mesh-like or finger electrode configuration, being likewise in contact with the liquid crystal medium; a third electrode is spaced by a dielectric medium from the second electrode, such third electrode being in either orthogonal or parallel relationship with the second electrode. Voltages are selectively applied to each of the second and third electrodes such that the stable state of the liquid crystalline layer is changed from the ordered (homeotropic) or clear state, to the disordered (focal conic) or dark state.
