Abstract
A method of manufacturing a compensator layer features forming first and second retardation foils by polymerizing or vitrifying liquid-crystalline material comprising liquid-crystal molecules in manner wherein the liquid-crystal molecules in the polymerized or vitrified liquid-crystalline material of the first and second retardation foils respectively exhibit first and second tilt angles which are respectively parallel to first and second planes that are normal to major surfaces of the foils and that are angled with respect to one another by an angle of 60–120 degrees.
