Abstract: Liquid crystal displays could make excellent flat-screen televisions and computer monitors, if their brightness didn't change so markedly with viewing angle. A new, simple way to improve this optical performance has been demonstrated, using grooves in one surface of the display. An electric field can be used to make liquid-crystal molecules click into place, parallel to the grooves, producing the twisted configuration that is needed for a display element to work.
