Abstract
A liquid crystal display device using an alignment film of ladder-type organosilicone polymer or cross-linking product of cross-linkable ladder-type organosilicone polymer makes a homogeneous liquid crystal orientation, irrespectively of the kind of the liquid crystal used, never lowers its orientation ability even when fusion-sealing or sealing of the liquid crystal device is made with glass or thermosetting resin, and makes a clear display owing to the alignment film being colorless. The alignment film is insoluble in the liquid crystal used.
