ABSTRACT:
Method for producing homogeneous surface alignment of liquid crystal materials by applying to the surfaces of transparent plates bounding a liquid crystal film a polymer which is subjected to a shear thinning technique to cause elongation and alignment of long chain polymers. In certain embodiments of the invention, the surfaces are coated with a polymer treated with a dichroic dye such that a polarizing film is formed adjacent the liquid crystal film. This eliminates the need for separate polarizers on opposite sides of a liquid crystal display.
