A new alignment method for liquid crystals was studied. A uniform alignment was obtained by the deposition of a polyimide film spread on the water surface on a glass substrate without rubbing process. The orientation of polymer chains was effected by stretching on the water surface. When the removal velocity of the film was higher, the alignment of polymer chains became higher, and the alignment quality of liquid crystal molecules became better. Even when the main chain of the polymer molecule was not linear, the higher ordering of the liquid crystal molecules was achieved.
