ABSTRACT:
An organic thin film obtained by spreading an organic substance comprising a polymer on a liquid surface, and compressing the spread substance unidirectionally or in two directions facing each other, in which organic thin film the principal chain of said polymer in the surface of the film has been oriented perpendicularly to the direction of the compression, and a method for producing the same. A liquid crystal display device comprising substrates, a polarizer, electrodes at least one of which is transparent, if necessary semiconductor substrates at least one of which is transparent, an orientation-controlling film and a liquid crystal layer, among which at least one of the polarizer, electrode, semiconductor substrate, orientation-controlling film and liquid crystal layer comprises an organic thin film. The orientation-controlling film may be an organic thin film in which the film-forming molecules have been uniformly oriented in a particular direction in the surface of the film. The present invention provides an oriented organic thin film, a liquid crystal display device with the oriented organic thin film and a thin and flexible liquid crystal display device.
