In a field effect twisted nematic mode liquid crystal display device the fraction of the total number of liquid crystal molecules assembled into helical structures having the same direction of twist is greatly increased over that found in the usual construction. A method of preparing the liquid crystal cell to ensure that virtually all of the molecules in the liquid crystal cell are assembled in helices having the same twist direction is also disclosed.
