The present invention provides a novel hybrid polymer that is effective for alignment layers for inducing alignment of liquid crystal media. The hybrid polymer of the present invention is selected from the group consisting of (a) polyimide, poly (amic acid), and one or more oligomers and one or more polymers within the types of these esters, and at least one At least one component comprising one initiator-generating group; and (b) at least one component selected from the group consisting of one or more addition monomers and one or more addition polymers; Are covalently bonded to form a copolymer. The invention further shows liquid crystal elements such as all liquid crystal display products or modes, liquid crystal devices, and liquid crystal optical films comprising a novel hybrid polymer alignment layer.
