Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To stably align liquid crystalline molecules in a perpendicular and uniform direction by applying an aq. soln. of a polyamic acid salt on a supporting body to form a coating film and rubbing the film surface. SOLUTION: An alignment film is formed from an aq. soln. of a polyamic acid salt. The polyamic acid is synthesized by partial condensation of tetracarboxylic acid and diamine. In order to align the liquid crystalline molecules perpendicularly, the function of side chains is more important than the main chain of the polyamic acid salt in the alignment film, and practically, the surface energy of the alignment film is decreased by the functional groups of the polymer to align the liquid crystal molecules perpendicular to the film. The rubbing treatment of the alignment film formed by applying an aq. soln. of a polyamic acid salt on the supporting body is carried out by rubbing the surface of the film containing modified polyvinylalcohol for several times in one direction with paper or cloth.
