ABSTRACT:
The present invention relates to a liquid crystal device driven by a linear coupling, such as ferroelectric and/or flexoelectric coupling, between an inhomogenous in-plane electric field generated by an electrode pattern over a first sub-volume of the bulk layer adjacent to said electrode pattern and liquid crystals in a polarized state comprised in said first sub-volume and/or in an optional alignment layer applied on said electrode pattern said polarization being stronger than any possible similar liquid crystal polarization of the bulk layer outside said first sub-volume, said alignment layer, and/or a second sub-volume of the bulk layer adjacent the inner surface of the other substrate, or an optional second alignment layer or an optional electrode pattern applied thereon.
