The investigation of the surface alignment of liquid crystal (LC) multilayers evaporated on photo-treated polyimide vertical alignment (PI-VA) film was carried out by means of the novel three-dimensional (3-D) surface profiler instrument. We report the first use of the surface profiler to visualize a microscopic image of the monolayer arrangement of LC 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 LC multilayers. It seemed that the topology of LC multilayers is indicating the orientational distribution of LC molecules. It is shown that there is a relationship between the bulk structure and the adsorbed mono-or multilayers.
