The Electro Spray Deposition (ESD) method is known as one of the techniques for forming a thin film. The dropletsof liquid solution are blasted out from a tiny capillary top are spit out again and again by the Coulomb force in a highelectric field. Then the droplets, smaller than one micron size, are caught and deposited on the substrate surface. The pre-tilt angle is one of the important parameters for the alignment of liquid crystals (LC). Our research grouphas attempted to apply the ESD method to forming the alignment film for the LC molecules. In this report, an improvedESD method which sprayed two solutions of alignment materials alternately has been proposed due to controlling thepre-tilt angle for the LC alignment in good reproducibility. Furthermore, to exemplify the advantage of our method, a270deg STN-LC cell which required a high pretilt angle was fabricated using this method.
