Abstract
The investigation of the surface alignment of liquid crystal multilayers evaporated on photoalignment polyimide film was carried out by means of the novel three–dimensional surface profiler instrument and the optical polarizing microscope. The purpose of this investigation is to visualize a microscopic image of the monolayer arrangement of liquid crystal molecules in contact with the surface of photoinduced polyimide film. From our experimental study, photoinduced anisotropy of partially photo–exposed polyimide film can be visualized as a topological image of liquid crystal multilayers. It seemed that the topology of liquid crystal multilayers is indicating the orientational distribution of liquid crystal molecules.
