The ESD method is known as one of the film forming methods. A solution is sprayed by repulsion of electrostaticforce and the tiny size of materials can be deposited on the substrate surface when a high voltage is applied betweenthe capillary and the substrate. In a previous our study, a bistable surface was fabricated, when PVCi was deposited byESD method on the substrate which was formed with horizontal alignment film, however, there is a problem with thequality of the forming film. In this report, novel methods to improve the conventional methods are proposed. Two capillaries and two kinds ofalignment materials are used. And, each solution of alignment material was sprayed from capillaries at the same time oralternately. The reproducibility of the film forming could be improved by these methods.
