An elongate implantable electrical line including an end component at one longitudinal end of the electrical line, wherein the end component includes at least one electrically conductive electrode surface electrically connected to the electrical line. One wall carries a surface treatment giving a first azimuthal alignment direction with or without a surface pretilt to liquid crystal molecules. A handle is axially fixed and rotatably coupled to the handle body second end. The surface modified film is then baked or calcined at a high temperature.
