Abstract
A method for orienting a liquid crystal comprises bringing a liquid crystal into contact with a heat treated surface of an electrode substrate provided with a film formed by coating a silane compound having alkoxy and an organic residue having at least a fluorine-substituted hydrocarbon residue, the heat treatment being effected under vacuum or under the conditions that the heating temperature and the treating time are within the region of a triangle having the vertexes at (1.75, 0), (2.5, 0) and (1.75, 3.7) in a coordinate with 1000 x (x being the reciprocal of absolute temperature) on the abscissa and ln k' on the ordinate where k' is the ratio of 300 min. to the treating time (min.). Liquid crystal display devices utilize the electrode substrate thus treated.
