substrate itself or an additionally applied material to form oriented relief or textural elements or certain shapes and grooves etc on the surface of the substrate to achieve this the method of photo lithography may be employed to create smaller elements alternatively the method of mechanical rubbing of the surface with a selected abrasive material may be employed during mechanical processing it is advised to pay attention to the necessity of removing possibly created particles and cracks on the substrate surface which could lead to distortions of the desired orientation other methods are also envisioned by the scope of the present invention since this example makes use of the properties of liquid crystals to orient in the channel during flowing application along the axis of the channel the necessary degree of orientation of supramolecular complexes on the substrate surface will be determined by the depth and directionality of the substrate surface relief in other words a certain degree of surface anisotropy is created on the substrate if required the relief may be created on one or more regions of the substrate and different regions can have different surface properties also there may be regions which do not promote orientation of the liquid crystal in one embodiment application of the liquid crystal film may be implemented via a method similar.
