Title: Method of preparing a liquid crystal display

Abstract: The inner surfaces of a pair of substrates of a liquid crystal display are treated with a solution of a surfactant to provide a uniform stable alignment of the liquid crystal material confined between the inner surfaces. The inner surfaces are first wetted by the soluton of the surfactant, a silane derivative, and the solution is then heated, while the inner surfaces are in contact with the solution, to a temperature between about 75.degree.C and a temperature just below the boiling point of the solution.
