The present invention provides novel hybrid polymer useful for alignment layers for inducing alignment of a liquid crystal medium. Hybrid polymers of this invention are prepared from a) at least one component selected from the group consisting of oligomer(s) and polymer(s) within the class of polyimides, poly(amic acids) and esters thereof wherein the at least one component comprises at least one initiator generating moiety, and b) at least one component selected from the group consisting of addition monomer(s) and addition polymer(s), wherein the two components are covalently bonded to form a copolymer. The invention further describes liquid crystal elements such as all liquid crystal display products or modes, liquid crystal devices and liquid crystal optical films comprising the novel hybrid polymer alignment layers.
